Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of curbstone paving equipment, and more specifically to an auxiliary positioning device for curbstone paving. Background Art
[0002] Curbstones are landmark stones installed between the road surface and other structures. Curbstones are generally required between the dividing strips and the road surface of urban roads, and between the sidewalk and the road surface. During the laying of curbstones, the straightness of the curbstone installation is an important indicator for testing the construction quality. During construction, a layer of cement mortar will be laid in the opened groove. The curbstone will be placed on the cement mortar, and the placed curbstone will be used as a reference. The auxiliary positioning device will be placed above the reference curbstone, so that the push rod in the auxiliary positioning device contacts the top of the reference curbstone, and the V-shaped push plate is driven to move by the push rod. The cement mortar next to the reference curbstone is leveled by the V-shaped push plate, and a groove for placing the curbstone is opened to ensure that the curbstones are laid on the same horizontal line.
[0003] However, most of the existing auxiliary positioning devices are pushed manually to make the push rod slide on the top of the reference curb. When the push rod moves along the reference curb, it will inevitably cause deviation, which will cause the groove for placing the curb pushed out by the V-shaped push plate to deviate, thereby making it impossible to ensure that the laid curbs are on the same horizontal line. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides a curbstone paving auxiliary positioning device to solve the problems raised in the above-mentioned background technology.
[0005] The utility model provides the following technical solutions:

[0008] One end of the bidirectional screw is connected to the rotating assembly, and the bidirectional screw can be driven to rotate through the rotating assembly.
[0009] The limit assembly includes a fixed box, a notch, a limit rod, a spring and a support rod. The top and bottom of the fixed box are both opened. One side of the fixed box is fixedly connected to one end of the fixed rod. The notch is opened on the side wall of the other side of the fixed box. The limit rod is arranged in the notch and slidably cooperates with the notch. One end of the limit rod is located outside the notch and inside the fixed box. One end of the support rod is fixedly connected to the limit rod, and the other end passes through the fixed box and slidably cooperates with the notch. The spring is sleeved on the support rod. One end of the spring is fixedly connected to the inner wall of the notch, and the other end is fixedly connected to the limit rod.
[0010] The connecting assembly includes a connecting rod and a plurality of fixing holes.

[0014] Technical effects and advantages of the utility model:
[0015] In the utility model, the bidirectional screw rod is driven to rotate by the rotating component. Because of the limitation of the slide groove, the two sliders drive the corresponding rollers to move along the slide groove and approach each other, so that the two rollers contact the two sides of the reference curb, thereby generating a positioning guide. When the fixed rod moves, it drives the support rod and the two rollers to move synchronously. The friction force causes the two rollers to roll along the two sides of the reference curb, ensuring the horizontal movement of the fixed rod, preventing the staff from pushing the support rod to deviate, and avoiding the deviation of the groove opened by the V-shaped push plate, thereby ensuring that the laid curb is on the same horizontal line.

DETAILED DESCRIPTION
[0021] The present invention is further described below in conjunction with specific embodiments. However, people familiar with the art should understand that the detailed description given here in conjunction with the drawings is for better explanation, and the structure of the present invention necessarily exceeds these limited embodiments. For some equivalent replacement schemes or common means, they are no longer described in detail herein, but still fall within the scope of protection of the present application.
[0022] Figure 1 to Figure 4 It is the best embodiment of the utility model, and the following Figure 1 ~Attached Figure 4 The utility model is further described.
[0023] The utility model discloses an auxiliary positioning device for laying curbstones, comprising a fixed rod 1 and a V-shaped push plate 2, a connecting component 3, a limiting component 4, an adjusting component 5 and two rollers 6, wherein the limiting component 4 is arranged at one end of the fixed rod 1, the connecting component 3 is slidably arranged on the limiting component 4, the V-shaped push plate 2 is connected to the connecting component 3, the adjusting component 5 is arranged below the fixed rod 1, and two moving wheels 8 are arranged at the bottom of the fixed rod 1;
[0024] The adjustment assembly 5 includes a support rod 501, a slide groove 502, a bidirectional screw rod 503 and two sliders 504. The fixed rod 1 and the support rod 501 are arranged crosswise, the top of the support rod 501 is fixedly connected to the bottom of the fixed rod 1, the slide groove 502 is opened at the bottom of the support rod 501, the bidirectional screw rod 503 is arranged in the slide groove 502, both ends of the bidirectional screw rod 503 are rotatably connected to the inner wall of the slide groove 502, and the two sliders 504 are threadedly sleeved on the bidirectional screw rod 503. The two sliders 504 are symmetrically arranged, and the two sliders 504 are slidably matched with the inner wall of the slide groove 502. The two rollers 6 are rotatably arranged on the corresponding sliders 504, and the threads at both ends of the bidirectional screw rod 503 are rotated in opposite directions.
[0025] One end of the bidirectional screw rod 503 is connected to the rotating assembly 7, and the rotating assembly 7 can drive the bidirectional screw rod 503 to rotate.
[0026] In the above structure, when in use, the staff lays cement mortar in the groove for laying the curbstone, and then the staff places the first curbstone in the groove, making the first curbstone a reference stone. At this time, the staff places the device on the top of the reference curbstone, and the two moving wheels 8 are in contact with the top of the reference curbstone. The staff rotates the rotating component 7, and the rotating component 7 drives the bidirectional screw rod 503 to rotate. Because of the limit of the slide groove 502, the two sliders 504 drive the corresponding rollers 6 to move along the slide groove 502 and approach each other, so that the two rollers 6 contact the two sides of the reference curbstone. When the fixed rod 1 moves, it drives the support rod 501 and the two rollers 6 to move synchronously. Because the friction force causes the two rollers 6 to roll along the two sides of the reference curbstone, ensuring that the groove opened by the V-shaped push plate 2 is flush with the reference curbstone;
[0027] The staff can adjust the position of the V-shaped push plate 2 according to the height of the reference curb. In the initial state, the connection component 3 is limited by the limit component 4. When adjusting, the limit component 4 no longer limits the connection component 3, and the connection component 3 drives the V-shaped push plate 2 to move along the limit component 4, so that the bottom of the V-shaped push plate 2 is at the same level as the bottom of the reference curb. The angle of the V-shaped push plate 2 is toward the reference curb and in contact with the reference curb. At this time, the connection component 3 is limited by the limit component 4, and the staff pushes the fixed rod 1 to make the V-shaped push plate 2 push the cement mortar next to the reference curb to open a flat groove for placing the curb, which is convenient for the staff to place the curb on the flat cement mortar later, so that the placed curb is at the same level as the reference curb.
[0028] The limiting assembly 4 includes a fixed box 401, a notch 402, a limiting rod 403, a spring 404 and a support rod 405. The top and bottom of the fixed box 401 are both opened. One side of the fixed box 401 is fixedly connected to one end of the fixed rod 1. The notch 402 is provided on the side wall of the other side of the fixed box 401. The limiting rod 403 is arranged in the notch 402 and slidably cooperates with the notch 402. One end of the limiting rod 403 is located outside the notch 402 and inside the fixed box 401. One end of the support rod 405 is fixedly connected to the limiting rod 403, and the other end passes through the fixed box 401 and slidably cooperates with the notch 402. The spring 404 is sleeved on the support rod 405. One end of the spring 404 is fixedly connected to the inner wall of the notch 402, and the other end is fixedly connected to the limiting rod 403.
[0029] The connecting component 3 includes a connecting rod 301 and a plurality of fixing holes 302. The connecting rod 301 is arranged in a fixing box 401 and slidably cooperates with the inner wall of the fixing box 401. The plurality of fixing holes 302 are all opened on one side of the connecting rod 301. The notch 402 can coincide with one of the plurality of fixing holes 302. The bottom of the connecting rod 301 is fixedly connected to the top of the V-shaped push plate 2.
[0030] In the above structure, when adjustment is required according to the height of the reference curb, in the initial state, the notch 402 coincides with one of the fixing holes 302, and the limit rod 403 is located in the corresponding fixing hole 302. At this time, the staff pulls the support rod 405, and the support rod 405 drives the limit rod 403 to move, and squeezes the spring 404, so that the limit rod 403 moves out of the fixing hole 302 and enters the notch 402. At this time, the staff moves the connecting rod 301 along the inner wall of the fixing box 401, and drives the V-shaped push plate 2 to move synchronously, so that the V-shaped push plate 2 enters the cement mortar, and the angle of the V-shaped push plate 2 contacts the reference curb and is at the same level as the bottom of the reference curb. When the fixing rod 1 moves, the V-shaped push plate 2 can push excess cement to both sides, and the cement mortar between the reference curb and the V-shaped push plate 2 in the initial state is cleaned manually.
[0031] The rotating assembly 7 includes a rotating rod 701 and a rotating disk 702 . One end of the rotating rod 701 passes through the supporting rod 501 and is fixedly connected to one end of the bidirectional screw rod 503 . The rotating rod 701 is rotatably connected to the supporting rod 501 , and the rotating disk 702 is fixedly connected to the other end of the rotating rod 701 .
[0032] The staff rotates the turntable 702, which drives the rotating rod 701 to rotate, and the rotating rod 701 drives the bidirectional screw rod 503 to rotate. When the use is finished, the staff rotates the turntable 702 in the opposite direction, and the turntable 702 drives the bidirectional screw rod 503 to rotate, so that the two sliders 504 respectively drive the corresponding rollers 6 away from each other, so that the two rollers 6 no longer contact the reference curb.
[0033] A handle 9 is fixedly mounted on the top of the fixing rod 1 .
[0034] The two moving wheels 8 are rotatably disposed at the bottom of the fixed rod 1 , and the bottom positions of the two moving wheels 8 are higher than the bottom position of the supporting rod 501 .
