Abstract
Description
Technical Field
[0001] The invention relates to the technical field of expansion joint construction, and in particular to auxiliary equipment for pavement expansion joint construction. Background Art
[0002] When processing the expansion joint of the road surface, a foam strip is pressed into the expansion joint to play the role of isolation and waterproofing, or to assist in the construction of the caulking material.
[0003] The conventional method is to manually press the foam strip into the expansion joint, which requires workers to pull the foam strip while pushing the roller pressing tool to press the lining strip into the slot. The workers need to bend over during the operation, which is labor-intensive. In addition, when pressing the foam strip into the slot, it is difficult to manually keep the foam strip parallel to the slot. When the foam strip deviates from the slot, the roller cannot contact the foam strip when rolling, and the roller tool needs to be returned to press the strip again, resulting in poor continuity of the pressing operation.
[0004] Moreover, during the process of pressing the foam strips, if there are debris, lumps or sharp edges in the slot, or if there are defects in the foam strips during the production process, the foam strips may be easily scratched by the debris or sharp edges in the slot when entering the slot, and may be easily broken under the squeezing of the rollers. The workers need to bend over to push the foam strips back into the slot, resulting in poor continuity and convenience of the pressing operation. Summary of the invention
[0005] In order to overcome the shortcomings that when the foam strip is pressed into the groove, it is difficult to keep the foam strip parallel to the groove manually, resulting in the roller being unable to contact the foam strip when rolling, and when the foam strip breaks, the worker needs to bend over and push the foam strip into the groove again, resulting in poor continuity and convenience of the pressing operation, the present invention provides an auxiliary equipment for the construction of pavement expansion joints.
[0006] Technical solution: An auxiliary equipment for the construction of pavement expansion joints, including a grip rod and a shell; a grip is provided on the grip rod; a shell is fixedly connected to the grip rod, and a guide wheel is rotatably connected to the shell; it also includes a sliding ring, a pulling tube, an extrusion wheel, a fixed roller, a winding wheel, a first driving member and an extrusion block; a sliding groove is provided on the inner side of the shell; an electric slider is slidably connected in the sliding groove, and a sliding ring is fixed to the electric slider; a pulling tube is detachably connected to the sliding ring, and the pulling tube is hollow inside; a strip-shaped through groove is provided on the pulling tube; a number of extrusion wheels are rotatably connected in the shell; a fixed roller is detachably plugged into the shell; a winding wheel is rotatably connected to the fixed roller, and a foam strip is wound on the winding wheel; the first driving member is fixedly connected in the shell; an extrusion block is fixedly connected to the telescopic end of the first driving member.
[0007] To further explain, a plurality of convex balls are arranged on the inner side of the pulling tube.
[0008] Further description, it also includes an elastic member; the sliding ring is slidably connected to the pulling tube, and a plurality of elastic members are fixedly connected between the sliding ring and the pulling tube.
[0009] To further illustrate, the diameters of all the extrusion wheels increase from right to left.
[0010] Further explanation: a button is provided at the handle of the grip.
[0011] To further explain, a plurality of abutting rollers are rotatably connected to the shell.
[0012] Further description: the grip of the grip is covered with an anti-slip layer.
[0013] To further illustrate, the side of the extrusion block in contact with the foam strip is configured as a concave arc surface.
[0014] Further description: a rotating wrench is provided on the fixed roller.
[0015] Further description, it also includes a second driving member and a cutter; the second driving member is fixedly connected to the shell; the cutter is slidably connected to the shell, and the cutter is directly opposite to the foam strip; the output end of the second driving member is fixedly connected to the cutter.
[0016] The beneficial effects of the present invention are as follows: the present invention realizes that the foam strip is squeezed downward by the squeezing wheel by continuously rolling to the right, and then the foam strip is pulled downward, and the winding wheel is driven to rotate adaptively, so as to gradually press the foam strip into the slot, thereby effectively facilitating manual operation of pressing the strip, without the need for multiple people to cooperate or manually bend over to operate, effectively saving manpower, and the squeezing wheel on the far right presses the foam strip into the slot, and then the multiple squeezing wheels on the left roll the foam strip again to ensure that the foam strip is completely pressed into the slot, and the diameters of all the squeezing wheels increase from right to left in sequence, thereby further enhancing the squeezing effect of the squeezing wheels on the foam strip;
[0017] The foam strip is limited by the pulling tube so that the foam strip can be kept parallel to the slit, so as to avoid the foam strip deviating from the slit, resulting in the failure of the extrusion wheel to contact the foam strip when rolling to the right, and then the failure of pressing the foam strip into the slit. At the same time, the sliding resistance between the pulling tube and the foam strip is increased by the convex ball in the pulling tube, so that the part of the foam strip located on the right side of the extrusion wheel is in a straight state, so as to avoid the foam strip being in a relaxed state, which makes it easy for the foam strip to deviate from the slit, thereby further ensuring that the extrusion wheel can normally contact the foam strip when rolling to the right.
[0018] When the foam strip is broken due to scratches by debris or sharp edges in the slot when entering the slot, and the part of the foam strip located between the pulling tube and the extrusion wheel is broken, the pulling tube drives the foam strip inside to move downward until the foam strip enters the slot, and then the extrusion block moves downward, passes through the strip-shaped through slot and contacts the foam strip, and then the extrusion block continues to move downward to press the end of the foam strip into the slot, and then the pulling tube is reset upward, the pulling tube and the foam strip slide relatively, and then the extrusion block is reset upward. Since part of the foam strip has been pressed into the slot at this time, the grip rod can be manually pushed to drive the present invention to move to the right, and the pressing operation on the foam strip can continue, thereby effectively ensuring the continuity and convenience of the pressing operation.

[0030] A plurality of convex balls are arranged inside the pulling tube 4 to increase the sliding resistance of the foam strip 111 in the pulling tube 4 .
[0031] It also includes an elastic member 5; the sliding ring 3 is slidably connected to the pulling tube 4, and four elastic members 5 are fixedly connected between the sliding ring 3 and the pulling tube 4, and the elastic members 5 are springs.
[0032] The diameters of all the extrusion wheels 6 increase sequentially from right to left.
[0033] A button 1001 is provided at the handle of the grip rod 1 , and the button 1001 is electrically connected to the sliding ring 3 and the first driving member 101 .
[0034] A plurality of abutting rollers 2001 are rotatably connected to the housing 2 .
[0035] The grip of the grip rod 1 is covered with an anti-slip layer to facilitate manual gripping.
[0036] The side of the extrusion block 102 in contact with the foam strip 111 is configured as a concave arc surface to enhance the extrusion and fixing effect of the extrusion block 102 on the foam strip 111 .
[0037] The fixed roller 7 is provided with a rotating wrench so that the fixed roller 7 can be manually twisted for loading and unloading operations.
[0038] like Figure 1As shown, with the side where the grip rod 1 is located as the left side, when working, the end of the foam strip 111 on the reel 8 is manually pulled out, the foam strip 111 is pressed against the guide wheel 2003, and after passing through the pulling tube 4, it is placed on the lower side of the extrusion wheel 6, and then the shell 2 and the parts connected thereto are placed on the upper side of the slot 222, and the shell 2 is placed parallel to the slot 222. At this time, the roller 2001 is pressed against the ground on the front and rear sides of the slot 222, and the end parts of the extrusion wheel 6 and the foam strip 111 are both located in the slot 222. 22, so that the handle 1 can be pushed manually, thereby driving the shell 2 and the parts connected to it to move from the leftmost side of the slot 222 to the right, and then as the extrusion wheel 6 continues to roll to the right, the foam strip 111 is squeezed downward by the extrusion wheel 6, and then the foam strip 111 is pulled downward, and the winding wheel 8 is driven to rotate adaptively, so that the foam strip 111 is gradually pressed into the slot 222, thereby effectively facilitating manual operation of pressing the strips, without the need for multiple people to cooperate or manually bend over to operate, effectively saving manpower.
[0039] When the shell 2 is manually pushed to move along the slot 222 to perform the pressing operation, the roller 2001 is pressed against the ground at the front and rear sides of the slot 222 to roll, thereby effectively reducing the resistance of the shell 2 to the right, and at the same time making the depth of the extrusion wheel 6 in the slot 222 consistent, thereby ensuring that the depth of the foam strip 111 pressed into the slot 222 is consistent, effectively ensuring the work quality.
[0040] It should be noted that when the shell 2 is manually pushed to move along the slot 222 to perform the pressing operation, the foam strip 111 is limited by the pulling tube 4, so that the foam strip 111 can remain parallel to the slot 222, so as to avoid the foam strip 111 deviating from the slot 222, resulting in the extrusion wheel 6 being unable to contact the foam strip 111 when rolling to the right, and further resulting in the foam strip 111 being unable to be pressed into the slot 222. At the same time, the sliding resistance between the pulling tube 4 and the foam strip 111 is increased by the convex ball in the pulling tube 4, so that the part of the foam strip 111 located on the right side of the extrusion wheel 6 is in a stretched state, so as to avoid the foam strip 111 being in a relaxed state, which causes the foam strip 111 to easily deviate from the slot 222, thereby further ensuring that the extrusion wheel 6 can normally contact the foam strip 111 when rolling to the right.
[0041] Since the foam strip 111 has a certain elasticity, the foam strip 111 is easy to bounce upward from the slot 222 again after being rolled only once, so multiple squeezing wheels 6 are provided, and the foam strip 111 is pressed into the slot 222 by the squeezing wheel 6 on the far right, and then the foam strip 111 is rolled again by the multiple squeezing wheels 6 on the left to ensure that the foam strip 111 is completely pressed into the slot 222, and the diameters of all the squeezing wheels 6 increase from right to left, thereby further enhancing the squeezing effect of the squeezing wheels 6 on the foam strip 111. At the same time, when the present invention moves to a portion where the width of the slot 222 is narrower, resulting in greater resistance to the foam strip 111 entering the slot 222, the grip 1 can be manually swung back and forth in a small amplitude to roll the foam strip 111 thereunder to the left and right by the squeezing wheels 6 to ensure that the foam strip 111 is completely pressed The foam strip 111 is pressed against the slit 222, but when the extrusion wheel 6 rolls the foam strip 111 to the left, the foam strip 111 on the right side of the extrusion wheel 6 is separated from the extrusion wheel 6 and becomes relaxed. As a result, when the extrusion wheel 6 moves to the right, the foam strip 111 is easily deviated from the extrusion wheel 6. Therefore, an elastic member 5 is provided. When the extrusion wheel 6 moves to the right to extrude the foam strip 111, the sliding resistance between the foam strip 111 and the pulling tube 4 drives the pulling tube 4 to slide downward on the sliding ring 3, and the elastic member 5 is stretched. When the extrusion wheel 6 moves to the left and separates from the foam strip 111, the elastic member 5 drives the pulling tube 4 to reset upward, and then drives the foam strip 111 to move upward through the pulling tube 4, so that the foam strip 111 is in a straight state, so as to avoid the deviation of the foam strip 111 from the extrusion wheel 6 when the extrusion wheel 6 moves to the right.
[0042] When there are debris, lumps or sharp corners in the slot 222, or there are defects in the foam strip 111 during the production process, the foam strip 111 is easily scratched by the debris or sharp corners in the slot 222 when entering the slot 222, and is broken under the squeezing action of the squeezing wheel 6 on the foam strip 111, that is, the part of the foam strip 111 located between the pulling tube 4 and the squeezing wheel 6 is easily damaged and broken, so when the foam strip 111 is broken at this place, the button 1001 can be manually pressed, such as Figure 5As shown, the electric slider in the control slide groove 2002 drives the sliding ring 3 to slide downward, and the sliding ring 3 drives the pulling tube 4 to move downward, thereby driving the foam strip 111 inside it to move downward through the pulling tube 4 until the foam strip 111 enters the slot 222, and then the first driving member 101 is controlled to push the extrusion block 102 downward, so that the extrusion block 102 passes through the strip-shaped through groove 4001 and contacts the foam strip 111, and then the extrusion block 102 continues to move downward to press the end of the foam strip 111 into the slot 222, and then The electric slider in the rear control slide groove 2002 drives the sliding ring 3 to reset upward, and then drives the pulling tube 4 to reset upward through the sliding ring 3, so that the pulling tube 4 and the foam strip 111 slide relative to each other, and then controls the first driving member 101 to drive the extrusion block 102 to reset upward. Since part of the foam strip 111 has been pressed into the slot 222 at this time, the handle 1 can be manually pushed to drive the present invention to move to the right, and the pressing operation on the foam strip 111 can continue, thereby effectively ensuring the continuity and convenience of the pressing operation.
[0043] When all the foam strips 111 on the reel 8 are pressed into the slots 222, the fixed roller 7 and the reel 8 can be manually removed from the housing 2, and then a new reel 8 can be installed on the housing 2 to continue the strip pressing operation.
[0044] Example 2
[0045] On the basis of Example 1, Figure 1-Figure 3 As shown, it also includes a second driving member 201 and a cutter 202; the second driving member 201 is fixedly connected to the shell 2, and the second driving member 201 is an electric push rod; the cutter 202 is slidably connected to the shell 2, and the cutter 202 is opposite to the foam strip 111; the output end of the second driving member 201 is fixedly connected to the cutter 202, and the second driving member 201 is electrically connected to the button 1001.
[0046] When the present invention moves to the end of the slot 222, the button 1001 can be manually pressed, such as Figure 3 As shown, the second driving member 201 is controlled to push the cutter 202 forward, and the foam strip 111 is cut by the cutter 202, so that the foam strip 111 on the winding wheel 8 is partially separated from the foam strip 111 in the groove 222, thereby facilitating the operation of pressing the foam strip 111 into the groove 222 of the next piece of road surface.
