Description

A manual hoist test system

technical field

The invention relates to the field of manual hoist tests, in particular to a manual hoist test system for testing the performance of manual hoists.

Background technique

The manual hoist has the advantages of compact structure, light weight, small size, easy to carry, safe and reliable, long service life and small pull (hand pull) force. It can carry out lifting, traction, lowering, lowering and other operations. If equipped with special devices, not only can it be used for non-linear traction operations, but also can easily select a suitable operating position, or double its load capacity with smaller tonnage machines. Manual hoists can be divided into chain hoists and manual hoists. There are two types of lever hoists. These two types of manual hoists are small in size and light in weight, and both meet the needs of the market. For the manual hoist that is widely used in industrial production, how to ensure the safety of personnel and equipment when testing the performance of the manual hoist and how to detect the safety performance of the manual hoist has become a problem.

Contents of the invention

The technical problem to be solved by the present invention is to provide a manual hoist test system to solve the problems in the prior art that the manual hoist performance test is broken or damaged, causing safety hazards to operators and equipment, and the manual hoist performance test is inefficient.

Further, the lower lump is set in the foundation pit, the upper lump is arranged above the lower lump, the upper center of the upper lump is provided with a first cylindrical protrusion, the center of the top of the first cylindrical protrusion is provided with a lifting lug, and the inner center of the upper lump is A deep hole is opened at the center, a first through hole is horizontally opened inside the first cylindrical bump, and a groove is opened at the bottom of the upper lump, one of the surfaces of the groove is a quarter of the spherical surface, and the other plane is the same as the deep hole. The axial direction is parallel, and the whole is a quarter of the sphere. There is a second cylindrical protrusion at the center of the upper part of the lower lump. The second cylindrical protrusion extends into the inside of the first cylindrical protrusion and has a second through hole at its end. The inner diameters of the first through hole and the second through hole are equal and the central axes are coincident. The upper part of the lower lump is provided with a protrusion. One of the surfaces of the protrusion is a quarter of a spherical surface, and the other two surfaces are mutually perpendicular planes. The whole is a quarter of a sphere, the lower surface of the protrusion is welded to the lower lump, and the protrusion and the groove are in a corresponding relationship in the vertical direction.

Further, the number of the first through holes, protrusions and grooves is at least 4, and the number of the second through holes is at least 2.

Further, the numbers of the first through holes, protrusions and grooves are all equal and twice the number of the second through holes.

The present invention has the following beneficial effects: Since the weight of the present invention adopts a combination of coaxial through holes and protrusions and grooves, the next performance test can be directly performed after a performance test is completed without moving the weight, which improves the performance of the manual hoist. The efficiency of the performance test is improved, and the potential safety hazard is also reduced.

Detailed ways

As shown in Figures 1, 2, 3, 4 and 5, a manual hoist test system is characterized in that it includes a foundation pit 21, the truss 3 is installed on the ground surface, and the hand pull driver 33 is arranged on the top of the truss 3, and the hand pull The driver 4 is set inside the truss 3 on the ground, the hook 3 is set in the center of the top of the truss 3, the control box 31 is set on the side of the middle of the truss 3, the control box 31 is connected with the hand drive 33 and the hand drive 4, and the connecting rod 52 is metal The bar is arranged vertically with the truss 3 and welded in the center of the top of the truss 3. The crossbeam 54 is arranged parallel to the ground and welded vertically on the connecting rod 52. The protective cover hook 51 is slidably connected with the crossbeam 54 through the roller 53 welded thereon to protect The cover 5 is a U-shaped metal plate, which is welded on the protective cover hook 51 , and the whole composed of the protective cover 5 and the protective cover hook 51 can slide along the beam 54 . The lower lump 2 is set in the foundation pit 21, the upper lump 1 is arranged above the lower lump 2, the upper center of the upper lump 1 is provided with a first cylindrical protrusion 15, and the center of the top of the first cylindrical protrusion 15 is provided with a lifting lug 13, There is a deep hole 11 at the inner center of the upper lump 1, a first through hole 12 is horizontally opened inside the first cylindrical protrusion 15, and a groove 14 is opened at the bottom of the upper lump 1, and one of the surfaces of the groove 14 is a spherical surface A quarter of the other plane is parallel to the axial direction of the deep hole 11, and the whole is a quarter of a sphere. The upper center of the lower lump 2 is provided with a second cylindrical protrusion 21, and the second cylindrical protrusion 21 extends into the To the inside of the first cylindrical protrusion 15 and its end is provided with a second through hole 22. The inner diameters of the first through hole 12 and the second through hole 22 are equal and the central axes coincide. The upper part of the lower lump 2 is provided with a protrusion 23. One of the surfaces of the protrusion 23 is a quarter of a sphere, and the other two surfaces are mutually perpendicular planes, and the whole is a quarter of a sphere. The lower surface of the protrusion 23 is welded with the lower lump 2, and the protrusion 23 and the concave The slots 14 are in a corresponding relationship in the vertical direction. The number of the first through holes 12 , the protrusions 23 and the grooves 14 is at least four, and the number of the second through holes 22 is at least two. The numbers of the first through holes 12 , protrusions 23 and grooves 14 are all equal and twice the number of the second through holes 22 .

When carrying out the performance test, first put the upper lump 1 on the lower lump 2, control the hook 32 to hook the lifting ear 13, move the protective cover 5 to the right, and then perform the performance test, so that the equipment can be avoided from breaking or being damaged during the test. Personnel and other equipment pose a safety hazard. At this time, the heavy lump of the performance test is the upper lump 1. After the test is completed, the upper lump 1 is put down through the hook 32. Since the lower portion of the upper lump 1 is provided with a groove 14, and the upper portion of the lower lump 2 is provided with a protrusion 23, the protrusion 23 can be opposite to each other. The groove 14 slides, and the protrusion 23 plays a position-limiting effect on the groove 14, so when the upper lump 1 is put down, the protrusion 23 is just completely placed in the groove 14, and the first through hole 12 and the second through hole 22 The axes coincide exactly. Use a steel rod to penetrate the first through hole 12 and the second through hole 22. At this time, the lower tuo 2 and the upper tuo 1 are combined into a whole by the steel rod. The control hook 32 hooks the lifting lug 13, and the upper tuo 1 and the lower tuo 2 are connected simultaneously. Movement, at this time the weight of the performance test is the upper lump 1 and the lower lump 2. After the test is finished, put down the lug 13, take off the steel rod, and remove the protective cover 5. In this way, after a performance test is completed, the next performance test can be directly carried out without moving the heavy lump.
