Description

Technical Field

[0001] The invention relates to the field of highway and municipal road construction, and in particular to a tool for highway and municipal road curbstone construction and a use method thereof. Background Art

[0002] With the continuous expansion of the national road network and the development of infrastructure, in order to ensure the overall linearity of the highway and the asphalt concrete paving on the edge without spilling and convenient compaction, curbstones are usually set on both sides of the roadbed of highways and municipal roads. The curbstones are generally cubic and made of granite. One piece is 1m long and weighs 60-80kg. Therefore, most of the installation is done manually, so the workers will bear a lot of weight and it is very difficult to carry. There is a 1cm gap between two adjacent curbstones, and it is not easy to control the linearity during installation. In addition, the curbstone is installed on the mortar. The mortar needs to be leveled before installation. When the curbstone is placed on the mortar cushion layer, it is found that the linearity or height is inconsistent. At this time, manual direct movement of the curbstone will cause the underlying mortar cushion layer to be damaged, and it needs to be leveled again, resulting in idle work and waste of materials. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a tool for highway and municipal road curb construction, which is convenient for carrying and installing curbs, keeps good linearity, is convenient for adjustment and speeds up construction, and a method for using the tool.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0005] A tool for highway and municipal road curb construction and a method of use, characterized in that it comprises:

[0006] The first support arm comprises a first force-applying rod, a first supporting rod and a first clamping rod connected in sequence; wherein, the first force-applying rod is horizontally arranged, the first supporting rod is inclined in a direction opposite to the first force-applying rod, and the first clamping rod is an arc structure with the convex surface of the arc facing the inclination direction of the first supporting rod.

[0007] The second support arm comprises a second force-applying rod, a second supporting rod and a second clamping rod connected in sequence; wherein, the second force-applying rod is horizontal and arranged at the same height as the first force-applying rod, the second supporting rod is inclined in a direction opposite to the second force-applying rod, and the inclination direction is opposite to that of the first supporting rod, the second clamping rod is an arc structure and the convex surface of the arc faces the inclination direction of the second supporting rod, the first support arm and the second support arm are hinged, and the hinge points are respectively located at the ends of the first supporting rod and the second supporting rod.

[0008] The clamping part includes a first clamping plate and a second clamping plate respectively fixed under the first clamping rod and the second clamping rod, and the first clamping plate and the second clamping plate both include a horizontal plate and a vertical plate fixedly connected on the sides, wherein the two horizontal plates are respectively connected to the first clamping rod and the second clamping rod, and the two vertical plates are relatively arranged and fixed on the sides farthest from each other of the two horizontal plates.

[0009] The protective pad is fixed on the first force applying rod and the second force applying rod and is rotatably connected to the first force applying rod and the second force applying rod respectively. The protective pad is an arc plate with the convex surface of the arc facing upward.

[0010] A further technical solution is that a pin is fixed to the middle of the protective pad, and the other end of the pin passes upward through the middle of the first force rod and the second force rod and is fixed with an anti-detachment head.

[0011] A further technical solution is that the fixing end of the pin shaft and the protective pad does not pass through the protective pad.

[0012] A further technical solution is that the clamping portion further comprises a linear plate vertically arranged and respectively perpendicular to the vertical plate and the horizontal plate, wherein the linear plate is fixed on one side of the vertical plate and the horizontal plate and an edge of the linear plate protrudes from the vertical plate.

[0013] A further technical solution is that the second support rods are two parallel to each other and are respectively located on both sides of the first support rod when hinged.

[0014] A further technical solution is that the exposed ends of the first force applying rod and the second force applying rod are both sleeved with rubber sleeves.

[0015] A further technical solution is that the method of using the highway and municipal road curb construction tool is as follows:

[0016] Step 1: The first force-applying rod and the second force-applying rod are held up by a worker respectively, and the curvature of the worker's shoulders is kept consistent with that of the protective pad;

[0017] Step 2: Clamp the two clamping parts under the first clamping rod and the second clamping rod at the two ends of the curb stone respectively, and keep the right angle formed by the horizontal plate and the vertical plate engaged with the edge of the curb stone;

[0018] Step 3: The worker lifts up the first force applying rod and the second force applying rod at the same time so that the clamping part clamps the curbstone and lifts it upward and moves to the designated position with the worker.

[0019] The beneficial effects of adopting the above technical solution are:

[0020] The problem of heavy curbstones and difficulty in manual handling was solved by using two arms to reduce effort and save manpower output.

[0021] A clamping portion is provided to match the edge of the curbstone, thereby increasing the force and ensuring that the device will not deviate or fall during transportation.

[0022] During use, effort is saved and the force is applied evenly without damaging the underlying mortar cushion layer.

[0023] And when a curbstone is found to be out of height or linear, it can be adjusted directly by clamping it through the reserved gap, without affecting the adjacent curbstones and without requiring any extra operations. The installation speed is fast, the quality is guaranteed, and it has great economic benefits.

[0024] Moreover, a rotatable pad is designed to increase the comfort of workers. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Figure 2 It is a main structural schematic diagram of the present invention. DETAILED DESCRIPTION

[0028] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on only the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] like Figure 1-2As shown, a tool for construction of road and municipal road curbstones and a method for use thereof, comprising a first arm 1, the first arm 1 comprising a first force-applying rod 11, a first support rod 12 and a first clamping rod 13 connected in sequence; wherein the first force-applying rod 11 is arranged horizontally, the first support rod 12 is inclined in the direction opposite to the first force-applying rod 11, and the first clamping rod 13 is an arc structure with the convex surface of the arc facing the inclination direction of the first support rod 12. A second arm 2, the second arm 2 comprising a second force-applying rod 21, a second support rod 22 and a second clamping rod 23 connected in sequence; wherein the second force-applying rod 21 is arranged horizontally and at the same height as the first force-applying rod 11, the second support rod 22 is inclined in the direction opposite to the second force-applying rod 21, and the inclination direction is opposite to that of the first support rod 12, the second clamping rod 23 is an arc structure with the convex surface of the arc facing the inclination direction of the second support rod 22, the first arm 1 and the second arm 2 are hinged, and the hinge points are respectively located at the ends of the first support rod 12 and the second support rod 22.

[0031] Thus, the first support arm 1 and the second support arm 2 together form a scissor-shaped structure for clamping and moving the curbstone, and the clamping part 3 used includes a first clamping plate and a second clamping plate respectively fixed below the first clamping rod 13 and the second clamping rod 23, and the first clamping plate and the second clamping plate both include a horizontal plate 31 and a vertical plate 32 fixedly connected at the sides, wherein the two horizontal plates 31 are respectively connected to the first clamping rod 13 and the second clamping rod 23, and the two vertical plates 32 are relatively arranged and respectively fixed on the farthest sides of the two horizontal plates 31. That is, the two vertical plates 32 and the two horizontal plates 31 respectively form a right-angle structure that matches the edges on both sides of the curbstone, so as to facilitate the clamping of the curbstone, increase the effective area, and ensure that it will not deviate or fall during transportation.

[0032] In addition, a protective pad 4 is fixed to the first force rod 11 and the second force rod 21. The protective pad 4 is connected in a rotatable design, and a pin 40 is fixed in the middle. The other end of the pin 40 passes through the middle of the first force rod 11 and the second force rod 21 upward and is fixed with an anti-slip head. The protective pad 4 is an arc plate with the convex surface facing upward. Therefore, when in use, the worker places his shoulders along the arc of the protective pad 4, and when moving, the protective pad 4 rotates with the movement of the worker's shoulders to ensure that it always plays a protective role. In order to ensure the comfort of the protective pad 4, the pin 40 and the fixed end of the protective pad 4 do not pass through the protective pad 4 and will not contact the shoulder.

[0033] In addition, in order to solve the problem of being unable to maintain linearity, the clamping part 3 also includes a linear plate 33 that is vertically arranged and perpendicular to the vertical plate 32 and the horizontal plate 31, respectively, and the linear plate 33 is fixed to one side of the vertical plate 32 and the horizontal plate 31, and the edge protrudes from the vertical plate 32. Therefore, the linear plate 33 and the vertical plate 32 work together with the horizontal plate 31 to clamp a corner point of the curbstone, and the protruding part of the linear plate 33 can also extend to the surface of the curbstone adjacent thereto at the same time, so that the two adjacent curbstones can be intuitively monitored and adjusted to maintain linearity.

[0034] Furthermore, in order to increase the strength of the clamping plate, the second support rods 22 are two parallel rods, and are located on both sides of the first support rod 12 when hinged. That is, when force is applied to the first force rod 11 and the second force rod 21, the hinge point and the action point are at the same place, and the action point will not be offset due to the fact that the second support rod 22 and the first support rod 12 are parallel to each other, thereby causing a loss of force.

[0035] In addition, in addition to the protective pad 4 , rubber sleeves are sleeved on the exposed ends of the first force application rod 11 and the second force application rod 21 .

[0036] A further technical solution is that the method of using the highway and municipal road curb construction tool is as follows:

[0037] Step 1: The first force-applying rod 11 and the second force-applying rod 21 are respectively held up by a worker, and the worker's shoulders are kept consistent with the curvature of the protective pad 4;

[0038] Step 2: Clamp the two clamping parts 3 under the first clamping rod 13 and the second clamping rod 23 at the two ends of the curbstone respectively, and keep the right angle formed by the horizontal plate 31 and the vertical plate 32 engaged with the edge of the curbstone;

[0039] Step 3: The worker lifts up the first force applying rod 11 and the second force applying rod 21 simultaneously so that the clamping part 3 clamps the curbstone and lifts it upward and moves to a designated position along with the worker.

[0040] The above are only preferred embodiments of the present invention. Any simple modification, deformation and equivalent substitution made by anyone to the present invention based on the contents of the present invention shall fall within the protection scope of the present invention.
