Abstract

The invention discloses an automatic locking hook, and relates to the technical field of mining equipment. The automatic locking hook comprises a hook block, a load-bearing block and a hanging block, wherein a hook hole is formed in the hook block; the middle part of the load-bearing block is a hollow accommodating cavity; a first threaded hole is formed in one end, which corresponds to the accommodating cavity, of the load-bearing block; a bolt penetrates in the first threaded hole and is rotatably connected with the hook block; a second threaded hole is formed in the other end, which corresponds to the accommodating cavity, of the load-bearing block; a bolt penetrates in the second threaded hole and is rotatably connected with the hanging block; the hanging block comprises a rotating part and a J-shaped hanging part; the rotating part is connected with the load-bearing block; and the hanging part is in contact with the load-bearing block rotatably. The invention aims to provide the automatic locking hook which is simple in structure, firm and practical.

Description

A kind of auto lock eave tile

Technical field

The present invention relates to mining equipment technical field, especially relate to a kind of auto lock eave tile.

Background technology

Centrifugal type slurry pump is one of important equipment of colliery and coal preparation plant, is widely used in the conveying operation of the liquid such as black water, recirculated water, sewage, coal slurry and heavy-media suspension, and its quantity is many, and model is many. Therefore, pump maintenance workload is large and complicated, keeps away unavoidably the hoisting hook of water pump accessory is drawn in maintenance process, does not have special lifting tool to bring great trouble and unsafe factor to maintenance work.

Because impeller, backplate, the spiral case profile of water pump are circular arc camber or irregular curved surface, and heavier, in the time removing and install water pump overcurrent components, with common gib head lifting impeller and spiral case, cannot firmly catch on water pump accessory, easily slippage in lifting process, causes and hangs thing and fall, cause security incident, buried hidden danger to safety in production. In order to ensure pump maintenance work safety, carry out smoothly, reduce worker's labour intensity, for its problem, design auto lock gib head has actual researching value.

Summary of the invention

Technical problem to be solved by this invention has been to provide a kind of auto lock eave tile of simple in structure, firm practicality.

For achieving the above object, the invention provides following technical scheme: a kind of auto lock eave tile comprises hook blocks, bearing block and hook hanging block; In described hook blocks, hook hole is set; The mid portion of described bearing block is the container cavity of hollow; Described bearing block arranges the first screwed hole in one end corresponding to container cavity, wears bolt and hook blocks is rotatably connected in the first screwed hole; Described bearing block arranges the second screwed hole at the other end of corresponding container cavity, wears bolt and be rotatably connected with hook hanging block in the second screwed hole; Described hook hanging block comprises the rotation section being connected with bearing block and is the hook hanging part of J type; Described hook hanging part can turn to bearing block and contacts.

Preferably, described bearing block arranges and departs from the radian that hooks hanging block away from one end of hook blocks.

Preferably, described radian is 15-30 °.

This auto lock eave tile is for water pump vane, spiral case and the design of backplate profile feature, different from the hook body of common gib head, is specifically designed to the lifting of slag stock pump water pump accessory. Easy to make, simple in structure, easy to use. This auto lock gib head is mainly made with steel plateelement, and in order to ensure its security reliability, the smallest cross-section area that hooks hanging part design is 30mm × 40mm, the weight of the hoisting object that can bear is 7 tons, general large pump accessory weight is 1 ~ 2 ton, therefore, reaches need of work. Can ensure to hook hanging part and can rotate as for bearing block and contact by hook blocks, bearing block and hook hanging block are to be rotatably connected by bolt setting in addition, arranging like this can make this auto lock eave tile tightly to hang tight in use by suspension hook object, and can unclamp easily by suspension hook object, very convenient when use. The bearing block of this eave tile arranges and departs from the radian that hooks hanging block away from one end of hook blocks, can more easily can be by suspension hook object. In addition, in actual mechanical process, find, in the time that radian is 15-30 °, can unclamp more easily by suspension hook object.

Brief description of the drawings

Fig. 1 is the dismounting platform structure schematic diagram of a kind of auto lock eave tile of the present invention;

Wherein, 1. hook blocks, 2. bearing block, 3. hook hanging block, 4. hook hole, 5. container cavity, 6. the first screwed hole, 7. the second screwed hole, 8. rotation section, 9. hook hanging part.

Detailed description of the invention

In order to deepen the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described, and this embodiment only, for explaining the present invention, does not form limiting the scope of the present invention.

Describe the preferred embodiment of the present invention in detail below in conjunction with accompanying drawing 1: a kind of auto lock eave tile comprises hook blocks 1, bearing block 2 and hooks hanging block 3; In described hook blocks 1, hook hole 4 is set; The mid portion of described bearing block 2 is the container cavity 5 of hollow; Described bearing block 2 arranges in one end of container cavity 5 correspondences wears bolt in the first screwed hole 6, the first screwed holes 6 and hook blocks 1 is rotatably connected; Described bearing block 2 arranges and in the second screwed hole 7, the second screwed holes 7, wears bolt and hook hanging block 3 and be rotatably connected at the other end of corresponding container cavity 5; Described hook hanging block 3 comprises the rotation section 8 being connected with bearing block 2 and the hook hanging part 9 that is J type; Described hook hanging part 9 can turn to bearing block 2 and contacts.

This auto lock eave tile is for water pump vane, spiral case and the design of backplate profile feature, easy to make, simple in structure, easy to use compared with the hook body of common gib head. This auto lock gib head is mainly made with steel plateelement, and in order to ensure its security reliability, hooking the smallest cross-section area designing hanging part 9 is 30mm × 40mm, the weight of the hoisting object that can bear is 7 tons, general large pump accessory weight is 1 ~ 2 ton, therefore, reaches need of work.

By by hook blocks 1, bearing block 2 with hook hanging block 3 and be to be rotatably connected by bolt setting and can ensure to hook hanging part 3 and can rotate as for bearing block 2 and contact, arranging like this can make this auto lock eave tile tightly to hang tight in use by suspension hook object, and can unclamp easily by suspension hook object, very convenient when use.

The bearing block 2 of this auto lock eave tile arranges and departs from the radian that hooks hanging block away from one end of hook blocks 1, can more easily can be by suspension hook object. In addition, in actual mechanical process, find, in the time that radian is 15-30 °, can unclamp more easily by suspension hook object.

Above-described is only the preferred embodiment of the present invention, it should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise of the invention, can also make some distortion and improvement, and these all belong to protection scope of the present invention.
