Description

Technical Field

[0001] This utility model relates to the field of engineering vehicle technology, and in particular to a trolley wiring harness tightening structure and a rock drilling trolley having the same. Background Technology

[0002] In engineering vehicles such as rock drilling rigs, hydraulic power is typically used for power output. Therefore, a large number of wiring harnesses are integrated into their telescopic booms. These harnesses are usually arranged along the length of the boom, and to accommodate the boom's extension and retraction, the length of the wiring harness along the boom is typically no less than the maximum length of the boom. When the boom retracts, the wiring harness extends beyond the boom, causing it to suspend. This makes it susceptible to scratches from the environment during boom swings, potentially leading to damage. Current technology often uses cable ties to secure the wiring harnesses, which is prone to instability, leaving the harnesses still suspended. Furthermore, replacing the wiring harnesses is extremely inconvenient. Utility Model Content

[0003] In view of the shortcomings of the above-mentioned prior art, this application provides a trolley wiring harness tightening structure and a rock drilling trolley having the same, which can tighten the wiring harness on the telescopic arm to prevent it from shaking and getting scratched or damaged, and has strong practicality.

[0004] To achieve the above objectives, the present invention employs the following technology:

[0020] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0021] like Figures 1-4 As shown, this example provides a trolley wiring harness tightening structure, including: a support plate 100 and a tightening assembly 200.

[0022] The support plate 100 is mounted on the telescopic arm of the trolley and arranged along its length. The tightening assembly 200 includes multiple bearing plates 201 located on one side of the support plate 100 and spaced apart along its length. The bearing plates 201 are L-shaped and used to support the wire harness. Their vertical sections are connected to the support plate 100, while their horizontal sections have a U-shaped plate 202 at the bottom. Two symmetrically arranged and coaxially rotatable clamping rods 203 are inserted through the U-shaped plate 202. The axes of the clamping rods 203 are parallel to the support plate 100. Along the length of 0, the upper end of the support plate 201 is provided with a tightening strap 204. One end of the tightening strap 204 is connected between the clamping rods 203. In use, the tightening strap 204 is wrapped around the lower clamping rod 203, then one end of the tightening strap 204 is passed between the two clamping rods 203, and then the tightening strap 204 is wrapped around the upper clamping rod 203. This can stably connect the tightening strap 204 and the clamping rod 203, so that the tightening strap 204 can be wound around the clamping rod 203 and tighten the wire harness.

[0023] Specifically, one end of the U-shaped plate 202 is bolted to the connecting plate 205, which is vertically arranged and installed at the bottom of the bearing plate 201.

[0024] Specifically, both sides of the U-shaped plate 202 are provided with through holes 208, and retaining rings 209 are inserted through the through holes 208. Clamping rods 203 are inserted through the retaining rings 209. The retaining rings 209 support the two clamping rods 203, and rotating the retaining rings 209 can drive the two clamping rods 203 to rotate synchronously. One end of the retaining ring 209 located inside the U-shaped plate 202 is provided with a limiting ring 210, and a stop bar 211 is provided on the outside of the limiting ring 210. One end of the stop bar 211 is rotatably installed on the side wall of the U-shaped plate 202, and the axis of rotation is parallel to the axis of the retaining ring 209. When the retaining ring 209 is installed in the through hole 208, the stop bar 211 can be deflected to one side. Under its own gravity, the stop bar 211 will be in a vertical state, thereby limiting the retaining ring 209 and preventing it from coming out of the through hole 208.

[0025] Specifically, ratchet 212 is provided on both outer sides of the U-shaped plate 202, and clamping rod 203 is inserted through the ratchet 212 and arranged coaxially. The end of the retaining ring 209 located outside the U-shaped plate 202 is provided with a positioning pin 213, which is inserted through the ratchet 212. This allows the ratchet 212 and retaining ring 209 to rotate synchronously directly under the action of the positioning pin 213, rather than rotating synchronously through the force transmitted by the clamping rod 203, making the rotation process smoother.

[0026] Specifically, ratchet 212 engages with pawl 216, pawl 216 is mounted on U-shaped rod 217, U-shaped rod 217 is sleeved on screw 218 and locked with nut, screw 218 passes through U-shaped plate 202, sleeve 219 is mounted on the inner side of U-shaped plate 202 and arranged coaxially with screw 218, torsion spring 220 is mounted on sleeve 219, the side of the protruding part of torsion spring 220 contacts U-shaped rod 217, under the action of torsion spring 220, pawl 216 always has a tendency to deflect, so ratchet 212 is locked, so that it always has a tendency to rotate in one direction, and after ratchet 212 is rotated at a certain angle, the tightening strap 204 can be tightened to ensure the bundling effect of wire harness, and it is also convenient to loosen the tightening strap 204 to replace wire harness tubing.

[0027] Specifically, a connecting block 214 is provided between the clamping rods 203 on the outside of the U-shaped plate 202. One end of the connecting block 214 abuts against the ratchet 212 to ensure the ratchet 212 is limited, thereby ensuring the stable meshing of the ratchet 212 and the pawl 216, and also facilitating the rotation of the pawl 212. For example, if the part of the connecting block 214 on the outside of the clamping rod 203 is set as hexagonal, then the clamping rod 203 can be automatically rotated by a device such as an air gun, which is more labor-saving and more efficient. It contacts the side of the clamping rod 203 facing its axis. Both sides of the U-shaped plate 202 are provided with pins 215 with bent ends. The pins 215 pass through the clamping rods 203, and one of the pins 215 passes through the connecting block 214. The two clamping rods 203 are locked by the pins 215 to prevent them from coming out of the ratchet 212 and the retaining ring 209.

[0028] Specifically, a section of the bearing plate 201 perpendicular to the side of the support plate 100 is provided with a through groove 206, and one end of the through groove 206 is provided through. Limiting plates 207 are provided on both sides of the through groove 206. The tightening strap 204 is located between the two limiting plates 207. The limiting plates 207 limit the wire harness placed on the bearing plate 201. When the wire harness is bundled with the tightening strap 204, the tightening strap 204 passes through the through groove 206 to ensure the bundling effect of the wire harness.

[0029] A rock drilling rig includes the rig wiring harness tightening structure described above.

[0030] Since the above are merely preferred embodiments of this utility model and are not intended to limit this utility model, it is obvious that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
