Description

Technical Field

[0001] This utility model relates to the field of winch installation technology for vehicle-mounted drilling rigs, and in particular to the winch fixing structure for vehicle-mounted drilling rigs. Background Technology

[0002] The winch of a truck-mounted drilling rig is an important component of the rig, mainly used for lifting and lowering drill bits and controlling their movement. Therefore, the secure installation of the winch is crucial. Existing winch fixing structures for truck-mounted drilling rigs (publication number CN205532284U) involve reinforcing the welded areas of the chassis frame before winch positioning. After the single-drum winch is positioned, the main longitudinal beam group fixing seats and the two side fixing seats of the winch frame are installed, namely the first, second, third, and fourth fixing seats, as well as the main longitudinal beam group positioning blocks. During installation, the first, second, third, and fourth fixing seats are welded to the square tube of the winch frame and connected to the chassis frame using bolts, washers, nuts, and lock nuts. After adjusting the bolts for fixation, the winch can be completely disassembled and returned to the factory for repair or replacement during later maintenance and replacement.

[0003] However, when the winch lifts the drilling tools, it is subjected to pressure at the bottom and tension at the top. If it is only fixed by the bottom bolts, the upper part of the winch frame may deform due to insufficient support. Deformation of the winch frame will affect the normal operation of the winch, reduce its working efficiency and service life, and may even lead to equipment damage or safety accidents. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art by proposing a winch fixing structure for vehicle-mounted drilling rigs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a winch fixing structure for a vehicle-mounted drilling rig, including a base. Two insert rails for connecting to the bottom of the winch are provided on one side of the upper surface of the base, and a raised beam is fixedly installed on the upper surface of the base near the middle. Both ends of the top edge of the raised beam are threaded with vertically arranged threaded rods. The top ends of the two threaded rods are inserted with the same auxiliary slide rail for connecting to the side of the winch. The insert rail near the raised beam is fixedly installed on the base, and the insert rail away from the raised beam is inserted into the base. One end of the insert rail is closed and a stop bar is inserted into the surface of the fixedly installed insert rail. A slider is embedded in the side of the raised beam, and a connecting arm that connects to the side of the slider is hinged to one side of the upper surface of the stop bar.

[0006] Preferably, the insert rail surface that is inserted into the base has a threaded lead screw, one end of which is rotatably mounted on the side of the insert rail that is fixedly connected to the base, and the insert rail surface that is inserted into the base is rotatably connected to a nut that is threadedly connected to the lead screw.

[0007] Preferably, a screw is rotatably connected to the side of the convex beam, the screw being arranged parallel to the insertion rail and threaded through the side of the slider.

[0008] Preferably, the bottom edge of the auxiliary slide rail is also rotatably connected to two nuts.

[0009] Preferably, two baffles parallel to the insertion rail are fixedly installed on the other side of the upper surface of the base, and several insertion blocks are inserted between the two baffles. An internal threaded cylinder is hinged to the upper surface of the insertion block, and an internal threaded stud is threaded to the opening of the internal threaded cylinder. A latching block for insertion with the side of the auxiliary slide rail is hinged to the top of the internal threaded stud.

[0010] Preferably, the two baffles are connected to insert plates on opposite sides, and the upper surface of the insert plates is U-shaped and connected to the side of the insert block.

[0011] Preferably, the insert is convex in shape.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, by setting up insert rails and auxiliary slide rails, sliding parts and sliding blocks that cooperate with insert rails and auxiliary slide rails are installed on the bottom and side of the winch, respectively. Therefore, when actually installing the winch, it is only necessary to adjust the distance between the two insert rails according to the size of the bottom of the winch. Then, the quick assembly and disassembly of the winch can be achieved by sliding the sliding block with the insert rail and sliding the sliding block installed on the side of the winch with the inner wall of the auxiliary slide rail. In addition, the insert rails and auxiliary slide rails can apply traction force to the bottom and side of the winch at the same time, which can prevent the winch from deforming.

[0014] 2. In this utility model, after the height of the auxiliary slide rail is adjusted, when placing the mounting block and the insert block from top to bottom, the mounting block is inserted into the auxiliary slide rail and the insert block is placed between the two baffles. Then, the insert plate is slidably installed, and the position of the insert block is fixed by the overlap between the insert plate and the upper surface of the insert block, which facilitates the oblique support and traction of the other side of the auxiliary slide rail.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] like Figures 1-4 As shown, the winch fixing structure of the vehicle-mounted drilling rig includes a base 1. Two insert rails 5 are provided on one side of the upper surface of the base 1 for insertion into the bottom of the winch. A raised beam 2 is fixedly installed near the center of the upper surface of the base 1. Vertically threaded rods 8 are threaded to both ends of the top edge of the raised beam 2. The tops of the two threaded rods 8 are inserted into the same auxiliary slide rail 9 for insertion into the side of the winch. In actual use, sliding parts and sliding blocks that cooperate with the insert rails 5 and auxiliary slide rails 9 are installed on the bottom and side of the winch, respectively. Therefore, during actual winch installation, only the distance between the two insert rails 5 needs to be adjusted according to the size of the winch bottom. Then, the quick assembly and disassembly of the winch is achieved by sliding the sliding block against the insert rails 5 and sliding the sliding block installed on the side of the winch against the inner wall of the auxiliary slide rail 9. Figure 1As shown, the insert rail 5 near the protruding beam 2 is fixedly installed on the base 1, and the insert rail 5 away from the protruding beam 2 is inserted into the base 1. The insert rail 5 inserted into the base 1 has a threaded rod 6 through its surface. One end of the rod 6 is rotatably installed on the side of the insert rail 5 fixedly connected to the base 1. In actual use, by rotating the nut 7 on the left insert rail 5, the left insert rail 5 can be moved relative to the right insert rail 5 to adjust the distance by utilizing the threaded connection with the rod 6. The insert rail 5 inserted into the base 1 has a nut 7 rotatably connected to the rod 6. In actual use, the height of the sliding block installed on the side will be different depending on the height of the winch. The bottom edge of the auxiliary slide rail 9 is also rotatably connected to two nuts 7. The two nuts 7 are respectively threaded to two threaded rods 8. Therefore, by selecting threaded rods 8 of different lengths and rotating the nuts 7 on the bottom edge of the auxiliary slide rail 9, the relative position of the auxiliary slide rail 9 and the threaded rod 8 can be fixed. The relative position of the auxiliary slide rail 9 and the protruding beam 2 can be fixed by utilizing the threaded connection between the threaded rod 8 and the protruding beam 2.

[0023] A stop bar 17 is inserted into the surface of the rail 5, which is closed and fixed at one end. A slider 14 is embedded in the side of the convex beam 2. A connecting arm 16, which is inserted into the side of the slider 14, is hinged to one side of the upper surface of the stop bar 17. A screw 4 is rotatably connected to the side of the convex beam 2. The screw 4 is set parallel to the rail 5 and threaded through the side of the slider 14. In actual use, the slider 14 can be moved on the surface of the convex beam 2 by rotating the screw 4. The slider 14 and the connecting arm 16 are connected by bolts. The connecting arm 16 can drive the stop bar 17 to move as the slider 14 moves. The stop bar 17 moves to abut against one side of the winch, while the other side of the winch abuts against the closed end of the rail 5, thus fixing the position of the winch.

[0024] Two baffles 3, parallel to the insertion rail 5, are fixedly installed on the other side of the upper surface of the base 1. Several insert blocks 10 are inserted between the two baffles 3. An internally threaded cylinder 11 is hinged to the upper surface of the insert block 10. An internally threaded stud 12 is threaded to the opening of the internally threaded cylinder 11. A latching block 13 for inserting into the side of the auxiliary slide rail 9 is hinged to the top of the internally threaded stud 12. An insert plate 15 is inserted on the opposite side of the two baffles 3. The upper surface of the insert plate 15 is U-shaped and inserts into the side of the insert block 10. The insert block 10 is convex. In actual use, depending on the height of the auxiliary slide rail 9, such as Figure 2As shown, by rotating and installing nut 7 at the opening of the internal threaded cylinder 11, and using the threaded connection between nut 7 and internal stud 12, the distance between insert block 10 and mounting block 13 can be adjusted by moving internal stud 12 within the internal threaded cylinder 11. The angle can be adjusted by the hinge swing of mounting block 13 and insert block 10. Therefore, after the height of the auxiliary slide rail 9 is adjusted, when placing mounting block 13 and insert block 10 from top to bottom, the mounting block 13 can be inserted into the auxiliary slide rail 9 and the insert block 10 can be placed between the two baffles 3. Then, the mounting plate 15 is slidably installed, and the position of insert block 10 is fixed by overlapping the upper surface of mounting plate 15 with the upper surface of insert block 10. This facilitates the oblique support of the other side of the auxiliary slide rail 9 and further fixes the auxiliary slide rail 9. In addition, the insert block 10 and mounting plate 15 used in this scheme are magnetically attracted.

[0025] The method of using this utility model is as follows: Sliding parts and sliding blocks that cooperate with the insert rail 5 and auxiliary slide rail 9 are installed on the bottom and side of the winch, respectively. The distance between the two insert rails 5 and the installation height of the auxiliary slide rail 9 are adjusted according to the size of the bottom of the winch and the height of the sliding block installed on the side of the winch. The winch is installed by inserting the sliding part into the insert rail 5 and the sliding block into the auxiliary slide rail 9. After the winch is installed, the stop bar 17 is installed to abut against the surface of the winch.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
