Description

Technical Field

[0001] This application belongs to the field of conductor rail technology, specifically relating to a conductor rail suspension device. Background Technology

[0002] A conductor rail suspension device is a specialized device for fixing conductor rail frames (plastic channels). Currently, commonly used suspension devices suspend and fix the conductor rail frame using hanging plates and bolts. The hanging plates are threaded onto the bolts and then inserted into the slots of the conductor rail frame, and then fixed with nuts. This type of suspension device has a simple structure, but during installation, it can only be inserted into the slots from both ends of the conductor rail frame. Considering that both ends of a conductor rail frame also need to be fixedly connected to other conductor rail frames through connecting plates and connectors, the suspension device must be installed first, followed by the connecting plates and connectors. This makes subsequent maintenance and replacement of the suspension device very troublesome. The connecting plates or connectors must be removed before the suspension device can be replaced and installed. Moreover, after installing the suspension device, the connecting plates or connectors must be reinstalled. Therefore, the installation of the connecting plates or connectors is very troublesome, time-consuming, and labor-intensive. Utility Model Content

[0003] This application provides a sliding contact line suspension device to solve the technical problem that the sliding contact line can only be inserted into the slots from both ends of the sliding contact line frame during installation.

[0004] The technical solution adopted in this application is as follows:

[0005] A sliding contact line suspension device includes a suspension bracket and a hanger rod. The suspension bracket has a through hole coaxial with the hanger rod. A base plate, an arm pair, a clamping assembly, and a locking pin assembly are sequentially arranged at the lower end of the suspension bracket. The base plate has a through hole coaxial with the hanger rod. The arm pairs are symmetrically arranged to form an installation gap. A horizontal channel and a vertical channel are sequentially arranged from top to bottom within the installation gap. The clamping assembly and the locking pin assembly are arranged on the vertical channel. The clamping assembly includes a clamping arm and an elastic hinge portion. One end of the elastic hinge portion is connected to the clamping arm, and the other end is connected to the inner wall of the arm pair by a bolt. The end of the clamping arm extends inward toward the elastic hinge portion to form a clamping foot, which is located on the vertical channel and abuts against a guide groove opened at the lower end of the vertical channel. The locking pin assembly includes a locking pin rod and a handle. An eccentric cam portion is provided in the middle of the locking pin rod, which abuts against a protruding stop block on a clamping arm. The hanger rod passes through the through hole and is connected to the lower part of the base plate by a nut.

[0006] Optionally, the elastic hinge includes a sleeve bolted to the inner side of the arm, a return spring and a connecting rod disposed inside the sleeve, one end of the connecting rod being connected to the clamping arm and the other end abutting against the return spring.

[0007] Optionally, a gear and a rack are provided between the locking pin and the handle. The gear is coaxial with the locking pin, and the rack is movably connected in a sliding groove opened vertically in the arm. A locking rod is provided at one end of the rack, and the locking rod is rotatably connected to the rack.

[0008] Optionally, the substrate has an annular reinforcing rib around the through hole, and the annular reinforcing rib is concentrically distributed with the through hole.

[0009] Optionally, the eccentric cam portion of the locking pin is an arc-shaped protrusion, the center of which is coaxial with the locking pin.

[0010] Optionally, the convex stop is a boss provided on the side of the clamping arm, which forms a planar contact fit with the eccentric cam portion.

[0011] Optionally, the hanger rod is a threaded rod, which passes through the through hole and is then locked to the bottom of the base plate by a nut.

[0012] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0013] 1. Through the planar engagement of the eccentric cam and the convex stop block, clamping and releasing can be achieved quickly and efficiently without the need for additional tools or long stroke adjustment, significantly improving installation efficiency;

[0014] 2. The combination of coaxial gears and racks provides mechanical advantages, and together with the locking rod, it can ensure a firm lock even in high vibration environments. Attached Figure Description

[0021] To more clearly illustrate the overall concept of this application, a detailed explanation is provided below with reference to the accompanying drawings.

[0022] Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below. It should be noted that, unless otherwise specified, the embodiments of this application and the features thereof can be combined with each other.

[0023] A sliding contact line suspension device includes a suspension bracket 1 and a hanger 2. The suspension bracket 1 has a through hole coaxial with the hanger 2. The lower end of the suspension bracket 1 is sequentially provided with a base plate 3, an arm pair 4, a clamping assembly 5, and a locking pin assembly 6. The base plate 3 has a through hole coaxial with the hanger 2. The arm pair 4 is symmetrically arranged to form an installation gap 7. A horizontal channel 71 and a vertical channel 72 are sequentially provided from top to bottom in the installation gap 7. The clamping assembly 5 and the locking pin assembly 6 are disposed on the vertical channel 72. The clamping assembly 5 includes a clamping arm 51 and an elastic hinge portion 52. One end of the elastic hinge portion 52 is connected to the clamping arm 51, and the other end is connected to the inner wall of the arm pair 4 by a bolt. The end of the clamping arm 51 extends inward toward the elastic hinge portion 52 to form a clamping foot 512. The clamping foot 512 is located on the vertical channel 72 and abuts against a guide groove 721 opened at the lower end of the vertical channel 72. The locking pin assembly 6 includes a locking pin rod 61 and a handle 62. The locking pin rod 61 has an eccentric cam part 611 in the middle, which abuts against a protruding stop block 511 on a clamping arm 51. The lifting rod 2 passes through the through hole and is connected to the bottom of the base plate 3 by a nut. The elastic hinge part 52 is located in the area between the clamping arm 51 and the arm pair 4.

[0024] Reference Figure 1 as well as Figure 2 When using the device in this solution, firstly, the hanger 2 is passed through the upper support structure of the factory building (such as the cable tray beam or the pre-embedded nut in the floor slab), so that the lower end of the hanger 2 extends out of the through hole of the base plate 3; then, the nut is tightened under the base plate 3 to realize the connection and positioning of the entire device with the upper structure.

[0025] Furthermore, the elastic hinge part 52 includes a sleeve 521 bolted to the inside of the arm pair 4. The sleeve 521 is provided with a return spring 522 and a connecting rod 523. One end of the connecting rod 523 is connected to the clamping arm 51, and the other end abuts against the return spring 522.

[0026] Furthermore, a gear 8 and a rack 9 are provided between the locking pin 61 and the handle 62. The gear 8 is coaxially arranged with the locking pin 61, and the rack 9 is movably connected in the sliding groove 41 opened vertically in the arm pair 4. A locking rod 10 is provided at one end of the rack 9, and the locking rod 10 is rotatably connected to the rack 9.

[0027] Furthermore, the substrate 3 has an annular reinforcing rib 11 around the through hole, and the annular reinforcing rib 11 is concentrically distributed with the through hole.

[0028] Example 1:

[0029] Reference Figures 1-4 In this embodiment, the clamping assembly 5 remains in its initial "open" state. After the hanging rod 2 is coaxially connected to the suspension bracket 1 and the base plate 3, the sliding groove is guided into the vertical channel 72. The operator grasps the handle 62 and rotates it clockwise (or counterclockwise), causing the locking pin 61 and the coaxial gear 8 to rotate. The eccentric cam 611 rotates accordingly, contacting the protruding stop block 511 on the side of the clamping arm 51, and prying the clamping arm 51 to move outward, causing the clamping foot 512 to move along the guide groove 721 and fit tightly against the side of the sliding groove. The rotation angle is adjusted according to the width of the sliding groove. During the rotation, the gear 8 drives the rack 9 to move laterally in the horizontal sliding groove 41. The locking rod 10 at its end can rotate to the locking position after clamping is completed to fix and lock the device.

[0030] When unlocking and releasing, first rotate the locking lever 10 in the opposite direction to the unlock position, then rotate the handle 62 in the opposite direction. The eccentric cam continues to press against the convex stop block 511 under the action of the return spring 522, driving the clamping arm 51 and the clamping foot 512 to move in the opposite direction along the guide groove 721 until the clamping foot 512 returns to the initial position, and the slide rail can be freely removed.

[0031] Example 2:

[0032] Reference Figure 1 as well as Figure 2 In this embodiment, the slide rail can also be horizontally inserted into the horizontal channel 71. Bolts are inserted through the pre-set bolt holes in the slide rail and the positioning holes on the horizontal channel 71, and then locked with nuts on the other side of the horizontal channel 71 to achieve horizontal positioning of the slide rail. Alternatively, the clamping assembly 5 from Embodiment 1 can be directly arranged within the horizontal channel 71, using the same eccentric cam + rack 9 mechanism to achieve the same quick-installation and quick-disassembly effect.

[0033] Furthermore, the eccentric cam portion 611 of the locking pin 61 is an arc-shaped protrusion, the center of which is coaxial with the locking pin 61.

[0034] Furthermore, the convex stop 511 is a boss provided on the side of the clamping arm 51, which forms a planar contact fit with the eccentric cam portion 611.

[0035] Furthermore, the lifting rod 2 is a threaded rod, which is inserted through the through hole and then locked to the bottom of the base plate 3 by a nut.
