Simple lifting device matched with pipe wrench

Abstract

The application discloses a simple and easy lifting tool matched with a pipe wrench, and belongs to the technical field of lifting tools, which comprises a sling mechanism, a connecting mechanism, an adjusting mechanism and a fixing mechanism. The application is novel in design and ingenious in device. In the lifting process, when the lifting hook drives the lifting ring to move upwards, rotation is generated between the first supporting plate and the second supporting plate through two chains, so that the distance between the two clamping blocks is reduced. At this time, the tension of the tension spring is stretched to a proper tension according to the diameter of the pipe wrench, and then the pipe wrench is stably clamped in the groove under the action of the clamping force and is lifted, so that the butt joint between the upper pipe and the lower pipe is implemented, thereby avoiding the difficulty in butt joint between the upper pipe and the lower pipe due to the heavy pipe wrench and manual operation, and further facilitating the construction of workers and improving the work progress.

Description

TECHNICAL FIELD

[0001] The application relates to a hoist technical field, in particular to a simple hoist matched with a pipe wrench. BACKGROUND

[0002] The main function of the pipe wrench is to reduce the labor intensity of workers and improve work efficiency. The pipe wrench can replace manpower to screw and unscrew drill rods and drilling tools, so that the screwing and unscrewing process is mechanized and automated, thereby reducing the labor intensity of the tripping operation and improving the production efficiency.

[0003] Specifically, the pipe wrench is widely used in pipeline engineering construction. It is usually matched with a threading machine and used for screwing and unscrewing pipeline fittings to realize mechanized operation and significantly improve the construction efficiency of industrial and agricultural pipeline engineering. In addition, the pipe wrench is also widely used in hydrogeological drilling, especially in large-diameter drilling. The effect of reducing labor intensity and shortening auxiliary time is particularly significant.

[0004] The purpose is to butt joint the upper pipe and the lower pipe by using the pipe wrench. The pipe wrench is heavy, so the hoist is arranged to hang the pipe wrench, thereby facilitating construction.

[0005] Therefore, the application provides a simple hoist matched with a pipe wrench. CONTENT OF THE UTILITY MODEL

[0006] The simple hoist matched with the pipe wrench is used to solve the problems in the background technology. During the lifting process, when the lifting hook drives the lifting ring to move upwards, the two chains drive the first supporting plate and the second supporting plate to rotate, so that the distance between the two clamping blocks becomes smaller. At this time, the tension of the tension spring is stretched to an appropriate tension according to the diameter of the pipe wrench. Then, under the action of the clamping force, the pipe wrench is stably clamped in the groove and is lifted, thereby realizing the butt joint between the upper pipe and the lower pipe. Therefore, the pipe wrench is difficult to butt joint between the upper pipe and the lower pipe due to the heavy weight and manual operation, thereby facilitating the construction of workers and improving the work progress.

[0007] In order to achieve the above purpose, the application adopts the following technical scheme:

The connecting mechanism is movably connected between the lifting cable mechanism and the adjusting mechanism. The adjusting mechanism is installed on the connecting mechanism. The fixing mechanism is fixedly connected to the connecting mechanism. The lifting cable mechanism comprises a lifting hook, a lifting ring and a chain.

[0009] As a preferred embodiment, the lifting ring is hung on the lifting hook, and two chains are arranged on the lifting ring.

[0010] The preliminary connection of the lifting ring and the lifting hook enables the lifting ring to lift the whole lifting tool, thus improving the practicability of the device.

[0011] As a preferred implementation form, the connecting mechanism comprises a first supporting plate, a second supporting plate, a through hole and a first connecting piece, the first supporting plate and the second supporting plate are arranged at the end of the chain away from the lifting ring through the through hole respectively;

[0012] When the lifting ring is lifted by the lifting hook, the rotation between the first supporting plate and the second supporting plate is generated by the two chains respectively, so that the distance between the two clamping blocks is reduced, thus improving the practicability of the device.

[0013] As a preferred implementation form, the first supporting plate and the second supporting plate are rotationally connected through the first connecting piece;

[0014] The rotation connection between the first supporting plate and the second supporting plate through the first connecting piece can expand the overall area of the fixed object and improve the use limit, thus improving the practicability of the device.

[0015] As a preferred implementation form, the adjusting mechanism comprises a tension spring and a second connecting piece, the top end of one of the tension springs is rotationally connected between the first supporting plate and the second supporting plate, and the bottom end is rotationally connected between the first supporting plate and the second supporting plate;

[0016] The rotation between the first supporting plate and the second supporting plate is generated by the top end and the bottom end of the tension spring respectively, thus improving the practicability of the device.

[0017] As a preferred implementation form, the top end of the other tension spring is rotationally connected between the first supporting plate and the second supporting plate, and the bottom end is rotationally connected between the first supporting plate and the second supporting plate;

[0018] The tension of the tension spring can be stretched to an appropriate tension according to the diameter of the pipe wrench, thus improving the practicability of the device.

[0019] As a preferred implementation form, the fixing mechanism comprises a mounting block, a clamping block, a first recess, a second recess and a third connecting piece, two mounting blocks are fixedly connected at the bottom of the first supporting plate and the second supporting plate respectively, and the clamping block is rotationally connected to the side close to the two mounting blocks through the third connecting piece;

[0020] Under the action of the clamping force, the pipe wrench is stably clamped in the recess and lifted, and the butt joint between the upper pipe and the lower pipe is implemented, thus avoiding the difficulty in butt joint between the upper pipe and the lower pipe due to the heavy pipe wrench and manual operation, and facilitating the construction of workers and improving the work progress, thus improving the practicability of the device.

[0021] As a preferred implementation, the inner part of each of the two clamping blocks is provided with a first groove and a second groove;

[0022] By setting the clamping block to be rotatable, the clamping block can be adjusted according to the actual use of the pipe wrench, cooperating with the first groove and the second groove, to ensure that the pipe wrench can be clamped, suitable for various pipe wrenches, improve the use limit, thereby improving the practicality of the device.

[0023] The beneficial effects of the present application are:

[0024] 1. The simple lifting device matched with the pipe wrench can make the distance between the two clamping blocks smaller when the lifting hook drives the lifting ring to move up, and the tension of the tension spring can be stretched to an appropriate tension according to the diameter of the pipe wrench, and then the pipe wrench can be stably clamped in the groove under the action of the clamping force, so that the upper pipe and the lower pipe can be connected, thereby avoiding the difficulty in connecting the upper pipe and the lower pipe due to the heavy pipe wrench and manual operation, facilitating the construction of workers, improving the work progress, and greatly improving the practicality of the device;
