Specific Embodiments

[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below. Apparently, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] Such as Figure 1 And Figure 2As shown in the figure, this embodiment provides a prefabricated cable trough installation tool, including a traveling mechanism 1, an operating rod 2, and a fixture 3. The operating rod 2 is installed on the traveling mechanism 1, and both ends of the operating rod 2 can swing up and down. The fixture 3 is connected to the front end of the operating rod 2. Among them, the fixture 3 includes two clamping arms 3.1 distributed in a cross shape. The two clamping arms 3.1 are rotatably connected to each other. A clamping plate 3.2 is arranged between the opposite sides of the bottom ends of the two clamping arms 3.1, and the top ends of the two clamping arms 3.1 are both connected to the front end of the operating rod 2.

[0021] The traveling mechanism 1 serves as the moving carrier of the entire prefabricated cable trough installation tool. Through the relative rotation of the bottom ends of the two clamping arms 3.1 of the fixture 3, the two clamping plates 3.2 can automatically clamp the prefabricated cable trough from both sides under the action of gravity. The worker presses down the tail end of the operating rod 2, making the operating rod 2 pivot around the traveling mechanism 1, and its front end tilt upward. At this time, the fixture 3 lifts the clamped prefabricated cable trough off the ground. Then, by using the displacement of the traveling mechanism 1, the position of the lifted prefabricated cable trough is adjusted. When lowering the prefabricated cable trough to the preset installation position, directly make the front end of the operating rod 2 swing downward, place the prefabricated cable trough at the preset installation position. At this time, the fixture 3 automatically releases the clamping force on the prefabricated cable trough, and the fixture 3 can release the prefabricated cable trough.

[0022] A hook 4 is arranged at the front end of the operating rod 2, and a suspension chain 5 is connected between the top ends of the two clamping arms 3.1. The suspension chain 5 is suspended on the hook 4. By using the suspension chain 5 to suspend the fixture 3 on the hook 4 at the front end of the operating rod 2, after the prefabricated cable trough is clamped by the fixture 3, when the front end of the operating rod 2 swings upward to lift the prefabricated cable trough, under the action of gravity, the two ends of the suspension chain 5 are subjected to inward pulling forces, making the fixture 3 tend to clamp the prefabricated cable trough. Furthermore, when transferring the prefabricated cable trough, under the action of the gravity of the prefabricated cable trough, the fixture 3 can stably clamp the prefabricated cable trough.

[0023] The traveling mechanism 1 includes a wheel axle 1.1 and wheel bodies 1.2 installed at both ends of the wheel axle 1.1. A support frame 6 is installed on the wheel axle 1.1, and the top end of the support frame 6 is sleeved on the operating rod 2. After the prefabricated cable trough is lifted, directly push the operating rod 2, and by using the traveling of the traveling mechanism 1 on the ground, the position of the prefabricated cable trough can be adjusted. After the fixture 3 clamps the prefabricated cable trough, using the support frame 6 as the rotation fulcrum of the operating rod 2 and combining with the lever formed by the operating rod 2, the lifting process of the prefabricated cable trough is more labor-saving.

[0024] A liftable backing plate 7 is arranged on the inner side surface of the clamping plate 3.2. A support rod 8 is rotatably installed on the outer side surface of the backing plate 7. One end of the support rod 8 is rotatably connected to a connecting rod 9, and the top end of the connecting rod 9 is rotatably connected to the clamping plate 3.2. Among them, the clamping plate 3.2 moves upward on the backing plate 7, making the support rod 8 support at the bottom of the side surface of the prefabricated cable trough.

[0025] Specifically, when the fixture 3 clamps the prefabricated cable trough, the clamping plate 3.2 makes the backing plate 7 closely adhere to the side wall of the prefabricated cable trough. During the process of lifting the prefabricated cable trough, the clamping plate will displace upward on the backing plate 7, the connecting rod 9 will pull the supporting rod 8 upward, and the end of the supporting rod 8 away from the connecting rod 9 will swing inward. Eventually, the supporting rod 8 will support at the bottom of the side wall of the prefabricated cable trough, that is, at the corner of the bottom of the side of the prefabricated cable trough, so that during the process of transferring the prefabricated cable trough, the supporting rod 8 assists in supporting the prefabricated cable trough and improves the stability when hoisting the prefabricated cable trough.

[0026] Among them, the supporting rod 8 includes a first rod body 8.1, a second rod body 8.2 and a third rod body 8.3. The first rod body 8.1 is perpendicular to the third rod body 8.3. The two ends of the second rod body 8.2 are respectively connected to the first rod body 8.1 and the third rod body 8.3. The end of the first rod body 8.1 away from the second rod body 8.2 is rotatably connected to the connecting rod 9. When the supporting rod 8 supports at the bottom of the side of the prefabricated cable trough, the second rod body 8.2 contacts the bottom of the side of the prefabricated cable trough, and the second rod body 8.2 is in a state where the bottom end inclines inward. The height of the third rod body 8.3 is less than the height of the prefabricated cable trough.

[0027] When lowering the prefabricated cable trough to the preset position, the third rod body 8.3 first contacts the ground. During the subsequent process of continuously lowering the prefabricated cable trough, the prefabricated cable trough squeezes the inclined second rod body 8.2 downward, causing the whole supporting rod 8 to displace outward. At this time, the supporting rod 8 causes the whole fixture 3 to displace outward to release the prefabricated cable trough.

[0028] A roller 10 is arranged on the lower surface of the third rod body 8.3. By arranging the roller 10, during the process of lowering the cable trough, when the third rod body 8.3 is under the pressure of the prefabricated cable trough, the roller 10 enables the supporting rod 8 to displace outward and withdraw from the bottom of the prefabricated cable trough more smoothly, and enables the fixture 3 to open to release the prefabricated cable trough.

[0029] A support plate 11 is vertically arranged at the bottom end of the backing plate 7. When the fixture 3 lowers to clamp the prefabricated cable trough, the support plate 11 will first support on the ground on both sides of the prefabricated cable trough to support the backing plate 7. As the fixture 3 continues to lower, the sliding rod 13 will move upward in the through groove 12 to a higher position, causing the top end of the connecting rod 9 to descend. The connecting rod 9 causes the top end of the supporting rod 8 to rotate inward, making the supporting rod 8 in a horizontal state to facilitate the fixture 3 to better clamp the prefabricated cable trough.

[0030] Furthermore, during the process of lifting the prefabricated cable trough, the clamping plate 3.2 displaces upward outside the backing plate 7, causing the connecting rod 9 to be pulled upward. The connecting rod 9 pulls the supporting rod 8, causing the supporting rod 8 to swing inward to support at the bottom of the side of the prefabricated cable trough.

[0031] The clamping plate 3.2 is provided with a through groove 12 distributed longitudinally, and a sliding rod 13 that penetrates the through groove 12 and can slide in the through groove 12 in the height direction is vertically installed on the outer side surface of the backing plate 7.

[0032] Specifically, in the initial state of the fixture 3, it is in a suspended state. At this time, through the cooperation of the sliding rod 13 and the through groove 12, the backing plate 7 is stably suspended on the clamping plate 3.2. The outer end of the sliding rod 13 penetrates the through groove 12 and extends outwards. With such a setting, during the process of lowering the prefabricated cable trough, when the supporting rod 8 is displaced outwards under the pressure of the prefabricated cable trough, the fixture 3 will release the prefabricated cable trough. At this time, the clamping arm 3.1 drives the clamping plate 3.2 to swing outwards. Furthermore, the length of the sliding rod 13 can be preferably applied during the outward swinging process of the clamping arm 3.1 to keep the through groove 12 always effectively sleeved on the sliding rod 13.

[0033] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
