Description

Technical Field

[0001] This utility model relates to the field of crane equipment technology, specifically to an auxiliary line frame for a miniature crane. Background Technology

[0002] A crane is a multi-action lifting machine that vertically lifts and horizontally moves heavy objects within a certain range. It is also known as an overhead crane, gantry crane, or hoist.

[0003] When a crane is lifting, it is usually controlled by an operator holding a remote control. The remote control is connected to the crane through a long wire harness. Since the lifting operation usually requires the operator to walk around the work area to observe and operate, and cannot get too close to the work area, the wire harness will be shaken and pulled by the operator during the lifting operation. Over time, the outer sheath of the wire harness is prone to wear and tear, which can cause the risk of electric leakage. Therefore, it is necessary to design an auxiliary wire frame to restrain the wire harness. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an auxiliary line frame for a miniature crane.

[0005] The technical solution adopted by this utility model to solve its technical problem is: An auxiliary line frame for a miniature crane includes a load-bearing beam, an end beam trolley mounted on top of the load-bearing beam, and an auxiliary line frame mechanism assembled with the load-bearing beam and the end beam trolley respectively. The auxiliary line frame mechanism includes a movable cross arm fixedly installed on one side of the end beam trolley, a square tube fixed to the movable cross arm by clamps and perpendicular to the ground, a support plate fixed to the lower end of the square tube by clamps, a fixed line support installed below the support plate for receiving wire bundles, several fixed cross arms equidistantly fixedly installed on the side of the load-bearing beam, a fixed rod fixedly installed with the fixed cross arms and parallel to the load-bearing beam, several movable line supports mounted below the fixed rods and sliding along the fixed rods, and a traction chain with one end attached to the movable line support at the first end and the other end attached to the fixed line support.

[0006] Preferably, a fixing flange is welded to one end of the moving cross arm facing the end beam trolley, and the fixing flange is fixed by screwing in bolts after contacting the end beam trolley; Furthermore, a limit frame is fixedly installed at the upper end of the moving cross arm by bolts.

[0007] Preferably, the fixed cable holder includes a fixed stud that runs from top to bottom through the holder plate, a fixed cable holder insulating pad and a fixed cable holder arc plate that are sequentially installed at the lower end of the fixed stud and limited by a nut.

[0008] Preferably, a partition plate is provided below the end of the fixed cross arm, which is fixed by bolts. A Z-shaped sheet metal part is fixed by bolts after it abuts against the partition plate. The Z-shaped sheet metal parts are symmetrical to each other and are suspended and fixed rods are installed.

[0009] Preferably, the lower surface of the fixing rod is cut in the middle, and the cut part is bent inward at 90° to form a guide wheel groove.

[0010] Preferably, the movable line holder includes a movable line holder fixing plate, two L-shaped plates symmetrically placed above the movable line holder fixing plate and fastened by pins, guide wheels mounted on both sides of the upper end of the two L-shaped plates by a fixing shaft, a movable line holder mounting stud that passes through the L-shaped plates and the movable line holder fixing plate from top to bottom, and a movable line holder insulating pad and a movable line holder arc plate that are mounted on the lower end of the movable line holder mounting stud and limited by nuts.

[0011] Preferably, a bolted fixing sleeve is welded to the side of the load-bearing beam near the auxiliary wire frame mechanism.

[0012] The beneficial effects of this utility model are as follows: 1. The limiting mesh frame can accommodate and restrict the wire harness, preventing it from swinging excessively or getting tangled with other components during movement. The insulating pads of the fixed wire support and the movable wire support avoid direct contact between the wire harness and metal parts, preventing the risk of short circuit due to wear and improving the electrical safety of the equipment. In addition, by having multiple movable and fixed wire supports jointly support the wire harness, the stress points of the wire harness are distributed, avoiding fatigue damage and breakage caused by long-term suspension or single-point stress in traditional methods. 2. When the end beam trolley moves, the traction chain and the movable line support work together to actively pull the first movable line support through the moving cross arm and traction chain. Subsequent line supports then follow smoothly in sequence under the pull of the chain and the line harness. This design ensures that the line harness is always lifted and moved in an orderly manner, rather than being dragged randomly on the ground or beam, which greatly reduces the possibility of wear, twisting and knotting of the line harness. In addition, the guide wheel of the movable line support slides in the guide wheel groove, ensuring low resistance and smoothness in the movement process. Attached Figure Description

Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0015] Example like Figure 1-6 As shown, an auxiliary wire frame for a miniature crane includes a load-bearing beam 1, an end beam trolley 2 mounted on top of the load-bearing beam 1, and an auxiliary wire frame mechanism 3 that is respectively assembled with the load-bearing beam 1 and the end beam trolley 2.

[0016] A bolted fixing sleeve 11 is welded to the side of the load-bearing beam 1 near the auxiliary wire frame mechanism 3. Specifically, after the fixed horizontal arm 35 is inserted into the fixing sleeve 11, the fixed horizontal arm 35 is pressed tightly by tightening the bolt, so that the fixed horizontal arm 35 can be fixedly installed.

[0017] The auxiliary wire frame mechanism 3 includes a movable cross arm 31 fixedly installed on one side of the end beam trolley 2, a square tube 32 fixed to the movable cross arm 31 by clamps and perpendicular to the ground, a support plate 33 fixed to the lower end of the square tube 32 by clamps, a fixed wire support 34 installed below the support plate 33 for receiving the wire harness, several fixed cross arms 35 equidistantly fixed on the side of the load-bearing beam 1, a fixed rod 36 fixedly installed with the fixed cross arms 35 and parallel to the load-bearing beam 1, several movable wire supports 37 assembled below the fixed rod 36 and sliding along the fixed rod 36, and a traction chain 38 with one end attached to the first movable wire support and the other end attached to the fixed wire support 34. Specifically, through the connection between the movable cross arm 31 and the end beam trolley 2, and the sliding of the movable wire support 37 along the fixed rod 36, the assembly consisting of the movable cross arm 31, the square tube 32, the support plate 33 and the fixed wire support 34 can automatically adjust the position of the wire harness as the end beam trolley 2 moves, ensuring that the wire harness maintains appropriate tension during movement and avoiding excessive bending or loosening.

[0018] A fixed flange 311 is welded to one end of the movable cross arm 31 facing the end beam trolley 2. After the fixed flange 311 contacts the end beam trolley 2, it is fixed by screwing in bolts. During the movement of the end beam trolley 2, the movable cross arm 31 can be moved along with it. The upper end of the moving cross arm 31 is fixedly installed with a limiting frame 312 by bolts. Specifically, the installation of the limiting frame 312 can accommodate and constrain the wire harness, prevent the wire harness from swinging, falling off or interfering with other components during movement, reduce the risk of mechanical damage to the wire harness and improve safety.

[0019] The fixed cable holder 34 includes a fixed stud 341 that runs from top to bottom through the holder plate 33, a fixed cable holder insulating pad 342 that is installed at the lower end of the fixed stud 341 and is limited by a nut, and a fixed cable holder arc plate 343.

[0020] It should be further explained that the wire harness can pass through the top of the insulating pad 342 of the fixed wire support, and the fixed wire support arc plate 343 is pushed up by rotating the nut, so that the fixed wire support arc plate 343 pushes up the fixed wire support insulating pad 342 and squeezes the wire harness, thus completing the fixing of the wire harness.

[0021] A partition plate 351, secured by bolts, is located below the end of the fixed horizontal arm 35. A Z-shaped sheet metal component 352, bolted to the partition plate 351, is symmetrically mounted and suspends the fixing rod 36. Specifically, the fixing rod 36 is suspended from the fixed horizontal arm by the partition plate 351 and the Z-shaped sheet metal component 352. This symmetrical structure provides uniform support, ensuring the fixing rod 36 is securely installed on the side of the load-bearing beam 1, capable of withstanding the weight of the wiring harness and dynamic loads during movement. Furthermore, the design of the Z-shaped sheet metal component 352 saves space, making the overall mechanism more compact and suitable for the limited installation environment of miniature cranes. The lower surface of the fixing rod 36 is cut in the middle, and the cut part is bent inward at 90° to form a guide wheel groove 361. The movable line holder 37 includes a movable line holder fixing plate 371, two L-shaped plates 372 symmetrically placed above the movable line holder fixing plate 371 and fastened by pins, guide wheels 373 mounted on both sides of the upper end of the two L-shaped plates 372 by fixing shafts, movable line holder through-studs 374 passing through the L-shaped plates 372 and the movable line holder fixing plate 371 from top to bottom, and movable line holder insulating pads 375 and movable line holder arc plates 376 that are fixed at the lower end of the movable line holder through-studs 374 and limited by nuts.

[0022] It should be further explained that the upper ends of the two L-shaped plates 372 are located inside the fixed rod 36, and the guide wheel 373 is located in the guide wheel groove 361, which allows the guide wheel 373 to slide stably along the guide wheel groove 361. During operation, the wire harness can pass through the top of the movable wire support insulating pad 375, and push the movable wire support arc plate 376 by rotating the nut, so that the movable wire support arc plate 376 pushes up the movable wire support insulating pad 375 and squeezes the wire harness, thus completing the fixation of the wire harness. When the end beam trolley 2 moves and moves the movable cross arm 31, the fixed wire support 34 uses the traction chain 38 to pull the first movable wire support to move, while the other movable wire supports slide in sequence under the pull of the wire harness.

[0023] The above embodiments of this utility model are not intended to limit the scope of protection of this utility model. The implementation of this utility model is not limited thereto. All other modifications, substitutions or alterations made to the above structure of this utility model based on the above content of this utility model and in accordance with the common technical knowledge and conventional means in the field, without departing from the basic technical idea of ​​this utility model, shall fall within the scope of protection of this utility model.
