Technical Field

[0001] This utility model relates to the field of pipeline construction technology, specifically to a hoisting device used for coal haulage pipeline construction. Background Technology

[0002] A coal chutes are pipeline systems used to transport coal from one location to another, enabling continuous and stable coal transport and improving production efficiency. Simultaneously, coal chutes also guide or divert coal during its descent, reducing dust generation. During the installation of coal chutes, pipe hoisting equipment is required. Pipe hoisting equipment refers to specialized lifting machinery used to lift pipes from the ground or other locations to a designated position for fixing and connection. Common types include steel pipe cranes, pipe hoists, pipe hoisting frames, and pipe hoisting slings. These equipment can achieve efficient and safe pipe hoisting operations based on different pipe types and hoisting environments.

[0003] Existing pipe hoisting frames typically use ropes to bind the pipes during the hoisting process, and then hook the ropes with hooks to achieve the hoisting effect. This hoisting method cannot achieve the effect of quickly fixing the pipes, resulting in more time required to complete the hoisting operation, reducing hoisting efficiency, and being inconvenient to use. Therefore, a new type of pipe construction hoisting equipment is proposed to solve the above problems. Utility Model Content

[0007] Furthermore, the support frame includes a base for bottom support, a sleeve for installation is fixedly connected to the base, an adjusting rod is rotatably connected inside the sleeve, and the top of the adjusting rod is fixedly connected to the lifting arm.

[0008] Furthermore, the adjusting rod is equipped with an adjusting disc, and the sleeve is equipped with a positioning disc that cooperates with the adjusting disc.

[0009] Furthermore, the number of adjustment holes is [number], and they are set at equal angles along the axis of the adjustment disc.

[0010] Furthermore, a reinforcing column is installed between the lifting arm and the adjusting rod for reinforcement.

[0011] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0012] I. This hoisting equipment for coal haulage pipeline construction is equipped with clamping components that enable it to automatically fix the pipes during hoisting without requiring manual fixing by workers.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1:

[0020] Please see Figure 1-3 This embodiment provides a hoisting device for coal haulage pipeline construction, comprising a support frame 1. A hoisting arm 12 for support is mounted on the top of the support frame 1. A pulley 14 is mounted at the end of the hoisting arm 12. A transmission device 15 for transmission is also mounted on the support frame 1. The transmission device 15 is connected to a traction rope 16, and the other end of the traction rope 16 passes around the pulley 14 and is fixedly connected to a clamping assembly 2.

[0021] The clamping assembly 2 includes a connecting platform 21, on which a connecting rod 22 is connected. Both ends of the connecting rod 22 are rotatably connected to a first adjusting arm 23 and a second adjusting arm 24. The other ends of the first adjusting arm 23 and the second adjusting arm 24 are respectively provided with a second linkage rod 26 and a first linkage rod 25. Both ends of the first linkage rod 25 and the second linkage rod 26 are rotatably connected to a first gripper 27 and a second gripper 28 for clamping. The first gripper 27 and the second gripper 28 are arranged crosswise, and the intersection is rotatably connected by a connector.

[0022] As a preferred technical solution in this embodiment, in actual use, the operator can place the pipe between the first clamp 27 and the second clamp 28, and then control the transmission device 15 to drive the traction rope 16 to generate a winding effect on the traction rope 16. During the winding process of the traction rope 16, the pulley 14 can ensure the sliding effect of the traction rope 16 and change the displacement direction of the traction rope 16, thereby achieving the effect of lifting the pipe. During the lifting process of the pipe, the connecting platform 21 is subjected to the upward traction force of the traction rope 16 and can generate an upward displacement effect, thereby driving the connecting rod 22 to change the angle between the first adjusting arm 23 and the second adjusting arm 24, so that the other ends of the first adjusting arm 23 and the second adjusting arm 24 move closer to each other, thereby driving the two second linkage rods 26 and the first clamp 27 to move closer to their connected ends, thereby achieving the effect of fixing the pipe at the other end.

[0023] The technical effects of the above embodiments are as follows: by setting the clamping component 2, the pipe can be automatically fixed during the hoisting process without the need for manual fixing by staff. At the same time, the pipe can be firmly clamped according to its own weight, ensuring its stability during the hoisting process.

[0024] Example 2

[0025] The support frame 1 includes a base 101 for bottom support. A sleeve 102 for installation is fixedly connected to the base 101. An adjusting rod 103 is rotatably connected inside the sleeve 102, and the top of the adjusting rod 103 is fixedly connected to the lifting arm 12. An adjusting plate 104 is provided on the adjusting rod 103, and a positioning plate 105 that cooperates with the adjusting plate 104 is provided on the sleeve 102. The adjusting plate 104 has multiple adjusting holes 106, and the positioning plate 105 has threaded holes that are adapted to the adjusting holes 106. Fixing bolts 107 for fixing are provided inside the adjusting plate 104 and the positioning plate 105. There are four adjusting holes 106, which are arranged at equal angles along the axis of the adjusting plate 104.

[0026] As a preferred technical solution in this embodiment: In actual use, when it is necessary to adjust the hoisting angle, the operator only needs to remove the fixing bolt 107 to cancel the limiting effect between the adjusting plate 104 and the positioning plate 105. Then, the adjusting rod 103 can be rotated to make the adjusting hole 106 on the adjusting plate 104 correspond to the threaded hole on the positioning plate 105. Then, the fixing bolt 107 can be reconnected to achieve the connection effect between the adjusting plate 104 and the positioning plate 105.

[0027] As a preferred technical solution in this embodiment, a reinforcing column 13 is provided between the lifting arm 12 and the adjusting rod 103 for reinforcement. In actual use, this arrangement can effectively ensure the reinforcement effect of the reinforcing column 13 during the lifting of the pipe, avoiding the situation where the weight of the pipe being lifted is too large and cannot be supported.

[0028] The technical effects of the above embodiments are as follows: by rotatably connecting the adjusting rod 103 to the sleeve 102, and by adjusting the plate 104 and positioning plate 105, the angle of the adjusting rod 103 can be adjusted. On the one hand, it can ensure that it is easy to install and remove during use, and on the other hand, it can ensure that the hoisting angle can be adjusted, thus ensuring its flexibility during use.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
