Description

Technical Field

[0001] The present application relates to the technical field of road construction, and in particular to a road spike construction device. Background Art

[0002] Narrow-gauge railways are widely used underground in mines. They are an important transportation facility with a wide range of uses. Generally, narrow-gauge railways directly serve various workplaces. Usually, railroad ties are used as track sleepers, and ordinary spikes are used as connecting and fixing devices between the sleepers and the tracks.

[0003] After placing the rails and tracks according to technical standards, the spikes are usually driven into the rails by hand using a sledgehammer. This method of using a sledgehammer to drive the spikes is labor-intensive and generally requires experienced workers with a certain technical foundation to carry out the work. It is prone to safety accidents such as injuries. The quality of construction depends largely on the personal experience of the construction workers, and the construction quality is uneven, and the construction efficiency is low.

[0004] Therefore, in view of the above technical problems, how to provide a road spike construction device with good safety, high efficiency and high construction quality is a technical problem that technical personnel in this field need to solve. Utility Model Content

[0005] The purpose of the present application is to provide a road spike construction device, which can constrain the nail portion of the road spike, ensure that the road spike is nailed into the road timber in an accurate posture, and at the same time can improve the construction efficiency and ensure the safety of construction personnel.

[0006] To achieve the above purpose, the present application provides a road spike construction device, comprising:

[0007] The limiting cylinder is hollow inside, and a through groove is opened on the side wall of the limiting cylinder. The spike extends into the limiting cylinder and slides along the axial direction of the limiting cylinder.

[0008] A power member, used for providing pressure for the spike to extend into the limiting cylinder;

[0009] A fixing frame, which is arranged on the side wall of the limiting cylinder and has an opening corresponding to the through groove on one side;

[0010] A clamping member is slidably arranged in the fixing frame and extends into or out of the limiting cylinder through the through slot, and a side of the clamping member facing the through slot is provided with an inclined surface matched with the head of the spike and a limiting slot matched with the spike portion of the spike;

[0011] The spike is pressed downward, and the nail portion extends into the limiting groove to limit the nail portion to move only along the axial direction of the limiting cylinder. The head portion presses the inclined surface to gradually move the clamp away from the limiting cylinder until the nail portion completely leaves the limiting groove and is nailed into the road log.

[0012] Preferably, the limiting cylinder is a hollow columnar structure, and the head is a disc matched with the inner wall of the limiting cylinder, so that the head can slide within the limiting cylinder.

[0013] Preferably, the power part is a pneumatic pick chisel, the pneumatic pick chisel is externally connected to a pneumatic pick, and the end of the pneumatic pick chisel is provided with a flat blunt head matching the head, so that the spike can be smoothly extended into the limiting cylinder.

[0014] Preferably, the outer edge of the end surface of the disk facing the inclined surface is provided with an outer chamfer matching the inclined surface.

[0015] Preferably, the groove cross-section of the limiting groove is a trapezoid, and the nail portion is inserted into the limiting groove along the lower bottom of the trapezoid and escapes from the limiting groove from the upper bottom of the trapezoid.

[0016] Preferably, the end of the clamping member extending into the interior of the limiting cylinder is an arc surface, and the axis of the arc surface is in the same direction as the axis of the limiting cylinder.

[0017] Preferably, the road spike construction device further comprises an elastic member, wherein the elastic member is located between the clamping member and the side wall of the fixing frame, and is used for providing an elastic force for the clamping member to slide toward the inside of the limiting cylinder.

[0018] Preferably, the elastic member is a spring and is symmetrically distributed between the clamping member and the fixing frame, and the spring is initially in a compressed state, and each of the springs is used to provide a maximum force of 50N for the clamping member.

[0019] Preferably, a handle is provided on the outer wall of the limiting cylinder.

[0020] Compared with the above-mentioned background technology, the present application uses a limiting cylinder to limit the position of the road spike to a certain extent, so that the road spike can be nailed into the road timber along the axial direction of the limiting cylinder, ensuring the accuracy of the nailing. At the same time, under the action of the clamping member, the nail portion of the road spike is further limited. Under the condition that the normal downward pressure of the road spike is not affected, the inclined surface and the limiting groove of the clamping member are used to gradually squeeze the inclined surface during the downward pressure process, so that the clamping member gradually separates from the limiting cylinder; at the same time, the nail portion will gradually separate from the limiting groove until the nail portion completely separates from the limiting groove and is nailed into the road timber. In other words, the nail portion is limited by the limiting groove, and the limiting of the head by the limiting cylinder greatly improves the construction quality of the road spike. At the same time, the personnel only need to keep the limiting cylinder stable, which improves the safety of the construction personnel and improves the construction efficiency.

[0021] Specifically, the device includes a limiting cylinder, a power member, a fixing frame and a clamping member. The limiting cylinder is hollow inside and has a through groove on its side wall. The spike extends into the limiting cylinder along the axial direction of the limiting cylinder and slides along the axial direction of the limiting cylinder, thereby being nailed into the road log. The power member provides pressure for the spike to extend into the limiting cylinder. The fixing frame is arranged on the side wall of the limiting cylinder, and one side has an opening corresponding to the through groove, so that the clamping member slidingly arranged in the fixing frame can extend into or out of the limiting cylinder through the through groove. At the same time, an inclined surface and a limiting groove are arranged on the side of the clamping member facing the through groove. During the pressing process of the road spike, the nail portion extends into the limiting groove, thereby limiting the nail portion to move only along the axial direction of the limiting cylinder, and the head presses the inclined surface, so that the clamping member will gradually move away from the nail portion while constraining the nail portion, and after the road spike moves to a certain extent, the clamping member will completely detach from the nail portion, thereby accurately nailing into the road log. The device can restrain the head and nail of the spike at the same time, ensuring that the spike is nailed into the road timber in an accurate posture, while improving construction efficiency and ensuring the safety of construction workers.

[0028] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0029] It should be noted that in this embodiment, the directions or positional relationships indicated by "upper", "lower", "front", "back", etc. are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present application. In addition, "first", "second", "third", and "fourth" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0030] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] like Figure 1 As shown, in this embodiment, a road spike installation device is provided, which includes a limiting cylinder 3, a power member 1, a fixing frame 5 and a clamping member 7. The limiting cylinder 3 is hollow inside, which is convenient for the road spike 2 to extend into, thereby playing a certain limiting role for the road spike 2. In other words, when the road spike 2 needs to be driven into the road timber, the road spike 2 is installed in the hollow structure of the limiting cylinder 3, so that the road spike 2 slides in the limiting cylinder 3 along its axial direction through the limiting role of the limiting cylinder 3.

[0032] Meanwhile, a through slot 31 is formed on the side wall of the limiting cylinder 3 , and the fixing frame 5 is arranged on the side wall of the limiting cylinder 3 , and has an opening corresponding to the through slot 31 on one side.

[0033] The power member 1 is used to provide pressure for the spike 2 to extend into the limit tube 3. In this embodiment, the power member 1 can be used in conjunction with a pneumatic pick commonly used in mine construction, using compressed air as a power source, without the need for complex preparations on the construction site. Of course, the power member 1 can also be a hydraulic power mechanism to provide pressure for the spike 2 to be driven into the railroad wood, and no further restrictions are made here, and all fall within the protection scope of this application.

[0034] Please refer to Figure 1 or Figure 2The fixing frame 5 of the present application is a rectangular frame with an opening at one end. The clamping member 7 is slidably arranged in the fixing frame 5. Since one side of the opening of the fixing frame 5 corresponds to the through-slot 31, the clamping member 7 can extend into or out of the limiting cylinder 3 through the through-slot 31. At the same time, an inclined surface 71 and a limiting slot 72 are arranged on the side of the clamping member 7 facing the through-slot 31. The inclined surface 71 cooperates with the head 21 of the spike 2, and the limiting slot 72 cooperates with the top of the spike 2.

[0035] Specifically, the inclined surface 71 is a surface that is approximately 30 degrees to the axis of the limiting cylinder 3. When the spike 2 is pressed down, the head 21 of the spike 2 will naturally press the inclined surface 71, so that the clamping member 7 gradually separates from the limiting cylinder 3. The limiting groove 72 is used to limit the nail portion 22 of the spike 2. That is, when the top portion extends into the limiting groove 72, the limiting groove 72 can limit the top portion to a certain extent, preventing the spike 2 from rotating in the limiting cylinder 3, thereby improving the accuracy of the spike 2 being driven into the railroad wood.

[0036] It should be noted that, since the road spike 2 needs to be nailed into the road timber, the limiting cylinder 3 can limit the head 21 during the gradual downward pressure of the road spike 2 to prevent the road spike 2 from axial shaking, and the limiting groove 72 can prevent the road spike 2 from radial sliding, thereby improving the accuracy of the road spike 2. The clamping member 7 will gradually separate from the limiting cylinder 3 during the continuous downward pressure of the head 21, so that the limiting groove 72 gradually separates from the constraint on the nail portion 22, until the nail portion 22 is completely nailed into the road timber. Of course, the setting of the clamping member 7 needs not to affect the downward pressure of the road spike 2, and the top of the road spike 2 should not be completely nailed into the road timber. Therefore, the present application adopts the setting method of the inclined surface 71, which can completely push the clamping member 7 away from the nail portion 222 through the head 21, thereby avoiding the influence of the clamping member 7 on the road spike 2.

[0037] In summary of the above embodiments, the present application uses the limiting cylinder 3 to limit the position of the road spike 2 to a certain extent, so that the road spike 2 can be nailed into the road timber along the axial direction of the limiting cylinder 3, ensuring the accuracy of the nailing of the road spike 2. At the same time, under the action of the clamping member 7, the nail portion 22 of the road spike 2 is further limited. Under the condition that the normal downward pressure of the road spike 2 is not affected, the inclined surface 71 and the limiting groove 72 of the clamping member 7 are used to gradually squeeze the inclined surface 71 during the downward pressure process, so that the clamping member 7 gradually separates from the limiting cylinder 3; at the same time, the nail portion 22 will also gradually separate from the limiting groove 72 until the nail portion 22 completely separates from the limiting groove 72 and is nailed into the road timber. In other words, the nail portion 22 is limited by the limiting groove 72, and combined with the limiting of the head 21 by the limiting cylinder 3, the construction quality of the road spike 2 is greatly improved. At the same time, the personnel only need to keep the limiting cylinder 3 stable, which improves the safety of the construction personnel and improves the construction efficiency.

[0038] The downward pressure mentioned above does not refer to a vertical downward pressure, but refers to the process of the road spike 2 moving axially along the limiting cylinder 3, so as to ensure that the road spike 2 can be smoothly nailed into the road rail; that is, no matter the road spike 2 is nailed into the road rail vertically, horizontally or obliquely, as long as the road spike 2 faces the road rail and is nailed into the road rail, it is called downward pressure.

[0039] It should be pointed out that the limiting cylinder 3 of the present application is a hollow cylindrical structure, and at the same time, the hollow structure thereof is also cylindrical, and the matching head 21 liquid level disc structure, of course, the two can be less-than-interference fit to ensure the smoothness of sliding of the spike 2 in the limiting cylinder 3, but it is necessary to ensure that the inner wall of the limiting cylinder 3 can play a certain axial limiting role on the disc structure to prevent it from deflecting, etc.

[0040] Of course, the limiting cylinder 3 may also be a rectangular structure, etc., as long as the structure of the head 21 matches it, thereby ensuring that a certain limiting effect can be achieved on the head 21 of the road spike 2. This will not be described in detail here, and all fall within the protection scope of this application.

[0041] In the above embodiment, it is pointed out that the power member 1 can be connected to a pneumatic pick, so the power member 1 here can be a pneumatic pick, and the pneumatic pick is connected to the pneumatic pick. At the same time, the end of the pneumatic pick is provided with a flat blunt head matching the head 21. For details, please refer to Figure 1 and Figure 2 The flat blunt head can match the head 21 of the spike 2, so that the spike 2 can enter the limiting cylinder 3 in a stable posture.

[0042] In addition, in order to enable the head 21 to smoothly extrude the inclined surface 71 and ensure that the two can be extruded smoothly, the end surface of the disc facing the inclined surface 71 is set to an outer chamfer whose outer circle matches the inclined surface 71, so that the outer chamfer contacts the inclined surface 71, ensuring that the two can be extruded smoothly, so that the clamping member 7 can stably detach from the limiting cylinder 3.

[0043] like Figure 3 or Figure 4 As shown, the cross-section of the limiting groove 72 of the present application is a trapezoidal structure. As pointed out above, an inclined surface 71 is provided on the clamping member 7. Therefore, under the premise of the inclined surface 71, the limiting groove 72 is provided on one side of the inclined surface 71, and naturally presents a certain trapezoidal structure; however, it should be noted that the trapezoidal structure may be an irregular trapezoid, but the overall structure needs to be a trapezoidal structure, so that the top is inserted into the limiting groove 72 along the lower bottom of the trapezoid and comes out of the limiting groove 72 from the upper bottom of the trapezoid.

[0044] It is worth noting that the clamping member 7 of the present application needs to extend into the limiting cylinder 3. Therefore, in order to ensure the extent to which the clamping member 7 extends into the limiting cylinder 3, the end of the clamping member 7 extending into the limiting cylinder 3 is an arc surface, at least ensuring that the end with the limiting groove 72 can be fully extended into the limiting cylinder 3, that is, the end of the clamping member 7 is aligned with the inner wall of the limiting cylinder 3, and ensuring that the top of the spike 2 can extend into the limiting groove 72. At the same time, the axis of the arc surface is in the same direction as the axis of the limiting cylinder 3, thereby ensuring that the arc surface and the inner wall of the limiting cylinder 3 have a certain degree of matching.

[0045] It should be noted that the limiting groove 72 is a through groove structure, which does not affect the top extending out of the limiting groove 72 and being nailed into the rail.

[0046] The road spike 2 construction device of the present application further includes an elastic member 6, which is located between the clamping member 7 and the side wall of the fixing frame 5. Figure 3 and Figure 4 , which can provide the clamping member 7 with an elastic force to slide toward the inside of the limiting cylinder 3, thereby ensuring that the clamping member 7 can remain against the nail portion 22 and preventing the clamping member 7 from arbitrarily separating from the nail portion 22, so that the limiting groove 72 cannot play a certain limiting role on the top.

[0047] Furthermore, the elastic member 6 of the present application is a spring, and the spring is symmetrically distributed between the clamping member 7 and the fixing frame 5. Figure 4 The spring is initially in a compressed state, and each spring is used to provide a maximum force of 50N for the clamping member 7, so that the clamping member 7 can be pressed against the nail portion 22. Of course, the elastic force provided by the spring can be selected according to actual conditions, and will not be described in detail one by one.

[0048] A handle 4 is provided on the outer wall of the limiting cylinder 3, which is convenient for construction workers to hold and fix the entire device, thereby ensuring the safety of construction workers. The length of the handle 4 is not described in detail here, and it is sufficient to ensure that it is located outside the safe distance. At the same time, the handle 4 can also be set on the fixing frame 5, and no more restrictions are made here.

[0049] When using the device, first put the spike 2 into the limiting cylinder 3. The limiting cylinder 3 limits the head 21 of the spike 2 to a certain extent. Due to the elastic force provided by the spring, the clamp 7 and the inner wall of the limiting cylinder 3, the spike 2 can be firmly constrained, that is, the spike 2 is constrained axially and radially at the same time. The construction personnel hold the handle 4 and align the construction road timber position with the nail portion 22 as the reference. The pneumatic pick is installed on the pneumatic pick, and the spike 2 is hit by the pneumatic pick, so that the spike 2 moves in the limiting cylinder 3. The spike 2 can limit its nail portion 22 in the clamping effect. At the same time, the clamp 7 will gradually separate from the limiting cylinder 3 during the downward movement of the spike 2 by using the inclined surface 71 of the clamp 7. That is, the clamp 7 gradually separates from the top of the spike 2. In this process, the clamp 7 gradually releases the constraint on the top, and the spike 2 is gradually and completely nailed into the road timber, so that the spike 2 is accurately nailed into the road timber.

[0050] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0051] Specific examples are used herein to illustrate the principles and implementation methods of the present application, and the description of the above embodiments is only used to help understand the method and core ideas of the present application. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the scope of protection of the claims of the present application.
