Description

A special clamp for rubber pier

technical field

The utility model relates to the field of fastening components, in particular to a special clamp for rubber piers, which is used for clamping and transporting rubber piers.

Background technique

As shown in Figure 3, during the storage of cast pipes, in order to prevent the cast pipes from colliding with each other and damaging the surface paint film, rubber piers are placed between the cast pipes for isolation. In the prior art, when placing the rubber pier, manual handling and stacking are used. This method has various potential safety hazards. In the process of manually stacking the rubber pier, one person is required to hold the rubber pier, and another person operates the handling equipment to stack. Cast pipes, a slight mistake will cause personal injury to the workers. Simultaneously, when a certain rubber pier needs to be taken out temporarily from the cast pipe that has been stacked, due to the existence of the extrusion force of the cast pipe, it will become very difficult to take it out manually.

Utility model content

The technical problem to be solved by the utility model is to provide a special clamp for rubber piers that makes stacking rubber piers safer and easy to use.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:

A special clip for rubber piers, comprising two symmetrically arranged clip arms with the same shape, the profile of the clip arms is arc-shaped, and a number of discontinuous pits are symmetrically arranged on the front and rear sides of the clip arms , the lower end of the clamp arm is provided with a first straight section, the upper end of the clamp arm is provided with a second straight section, the middle part of the two clamp arms is also hinged with the two ends of a cross bar, and the two A swing link is hinged on the second straight section of each clamp arm, and the other end of the swing link is hinged with the two ends of a handle.

The further improvement of the technical solution of the utility model is that: a thimble is installed on the middle part of the cross bar through a screw thread, the tip of the thimble is vertically downward, and a rectangular frame-shaped handle is installed on the top of the cross bar.

The further improvement of the technical solution of the utility model is that: a long splint with a trapezoidal cross section is fixedly installed on the inside of the first straight section of the two clamp arms, and several horizontal splints are evenly arranged on the inside of the splint. Non-slip texture.

The further improvement of the technical solution of the utility model lies in that two rubber sleeves are set at the hinged position between the two ends of the handle and the swing rod.

Owing to having adopted above-mentioned technical scheme, the technical progress that the utility model obtains is:

The utility model is a device specially used for stacking rubber piers. During use, the rubber piers can be clamped only by the weight of the rubber piers, so that the transportation of the rubber piers becomes very convenient. At the same time, the use of hands to support the rubber pier is avoided in the process of stacking the rubber pier, which improves the safety of the operation process.

The clamp arm in the utility model adopts a circular arc design, and at the same time, a groove is opened on the clamp arm. This design can effectively reduce the internal stress caused by casting on the premise of ensuring the casting strength of the clamp arm, and at the same time reduce the clamping force. arm weight. The arc-shaped jig arm can also improve the stress condition of the jig arm, making it more durable.

The utility model is also provided with a thimble for positioning the rubber pier and a splint with anti-skid lines, through these two devices, the rubber pier can be well fixed to prevent the rubber pier from being deflected or falling off during the transportation process. .

The handle in the utility model is also equipped with a rubber sleeve, which can effectively prevent the workers from pinching their hands in the process of pulling the handle, and further improves the safety of the utility model in use.

detailed description

Below in conjunction with embodiment the utility model is described in further detail:

As shown in Fig. 1 and Fig. 2, it is a structural diagram and a use state diagram of the utility model. The utility model is a clamp specially used for clamping rubber piers, which mainly includes two clamping arms 1 which are arranged symmetrically to each other and have the same shape.

The clamping arm 1 is a long beam with a substantially arc-shaped outline. A small straight section is provided at the lower end of the arc-shaped profile of the clamp arm 1 , which is called the first straight section 101 . Correspondingly, a small straight section, called the second straight section 102 , is also provided on the upper end of the arc-shaped profile of the clip arm 1 . The material of the clamp arm 1 is cast iron. In order to prevent the casting stress of the clamp arm 1 during the casting process, the front and rear sides of the clamp arm 1 are symmetrically provided with some long grooves with a rectangular cross section, and the grooves are discontinuous. . Such a structure can also reduce the weight of the clamp arm 1 without affecting the strength of the clamp arm 1, making the operation more convenient for workers.

The second straight section 102 of the clamp arm 1 is hinged with a swing rod 2 through a pin, and the swing rod 2 can swing up and down around the pin. The other ends of the two swing bars 2 and the two ends of the handle 3 are hinged to each other by pins. A cross bar 4 is installed in the middle of the two clamp arms 1, and both ends of the cross bar 4 are fixed on the clamp arms 1 in a hinged manner. When in use, the distance between the second straight sections 102 of the two clamp arms 1 can be increased by pulling the handle 3. At this time, the cross bar 4 serves as the fulcrum of the clamp arms 1, and the first of the two clamp arms 1 The straight section 101 will shrink inwards to clamp the rubber pier. At this time, when the handle 3 is lifted, the rubber pier will be firmly clamped between the first straight sections 101 of the two clamping arms 1 under the action of its own gravity.

In order to prevent the rubber pier from being dislocated or tilted during the clamping and transporting process, a thimble 5 is installed in the middle part of the cross bar 4 of the utility model, and the tip of the thimble 5 is vertically downward and screwed on the cross bar 4 by threads superior. The thimble 5 can withstand the upper surface of the rubber pier to prevent the rubber pier from swinging. Simultaneously, the inboard of the first straight section 101 of the two clamping arms 1 of the present utility model is also equipped with a long bar-shaped splint 6 with a trapezoidal horizontal surface. Next, the rubber pier will be better defined between the two clamp arms 1, and the anti-slip pattern can also effectively increase the friction between the splint 6 and the rubber pier to prevent the rubber pier from slipping.

Considering that when a worker holds the handle 3 in use, the handle 3 and the swing rod 2 are likely to crush the worker's hand, the utility model also sets two rubber sleeves at the hinged position of the handle 3 and the swing rod 2 7. Effectively guarantee the safety of workers when using it. At the same time, a handle 8 is welded on the top of the cross bar 4. The worker can hold the handle 3 and the handle 8 with one hand at the same time, and the two clamp arms 1 can be opened after kneading, and then they can be easily released. Rubber piers.

Another way of using the utility model is to tie a rope on the handle 3, and the other end of the rope is connected with a counterweight or another special clip for rubber piers. When stacking the rubber pier, put the rope on the cast pipe, and pull the handle 3 through the counterweight at the other end. At this time, the worker can leave the rubber pier, away from the cast pipe being lifted, and further lift the cast pipe The safety of operations during stacking.
