A type of elevation positioning stake for road and bridge construction

Abstract

This application provides an elevation positioning pile for road and bridge construction, including a positioning mechanism. The positioning mechanism includes an arc-shaped arm, with positioning shafts fixed at both ends. Protective sleeves are fitted onto the top and bottom of the positioning shafts. A support frame is fixed at the bottom center of the arc-shaped arm. A positioning insert is slidably connected inside the support frame. A support shaft is pinned to the top of the positioning insert. A limit groove is provided inside the support frame. The key technical point is that by contacting the protective sleeve fitted onto the outside of the positioning shaft with the outer wall of the pier, and then inserting one end of the positioning insert into the ground, a striking tool is used to strike the impact plate, causing the positioning insert to be inserted into the ground. As the positioning insert slides, it drives the support frame to move downwards, making the bottom end of the support frame flush with the bottom end of the pier and in contact with the ground. This ensures that the axial direction of the second connecting plate is the same as the axial direction of the pier, facilitating subsequent height marking work on the surface of the pier using an elevation mechanism.

Description

Technical Field

[0001] This invention belongs to the field of road and bridge construction technology, specifically a level positioning pile for road and bridge construction. Background Technology

[0002] In simple terms, road and bridge construction includes road construction and bridge construction. It generally includes the main roadbed engineering, borrow pits and spoil heaps, slope protection and embankment, comprehensive roadbed drainage, roadbed protection and reinforcement, embankment and cut roadbed, roadbed in special engineering geological areas, construction in winter and rainy seasons, as well as the construction organization of earthwork projects caused by roadbed construction, roadbed repair, quality inspection, and project acceptance. In the process of road and bridge construction, in addition to positioning and measuring distances on the ground, it is also necessary to measure the elevation of the roadbed, bridge piers, etc. in the vertical direction in order to build roads and bridges that meet the needs of use.

[0003] The current method of determining the elevation of road and bridge construction mainly relies on construction workers using lifting equipment and measuring tapes for measurement and marking. In actual construction, on the one hand, the flatness of the surrounding ground makes it difficult to place the lifting equipment horizontally on the ground; on the other hand, the method of construction workers using lifting equipment and measuring tapes for measurement and marking is inefficient. Summary of the Invention

[0004] To overcome the shortcomings of existing technical solutions, this application provides an elevation positioning pile for road and bridge construction. By contacting the outer wall of the pier with the protective sleeve fitted outside the positioning shaft, and then inserting one end of the positioning plate into the ground, the positioning plate is inserted into the ground by striking the impact plate with a striking tool. When the support shaft slides inside the limiting groove, it drives the support frame to move to the bottom, so that the bottom end of the support frame is flush with the bottom end of the pier and in contact with the ground. This ensures that the axial direction of the second connecting plate is the same as the axial direction of the pier, which facilitates the subsequent height marking work on the surface of the pier using an elevation mechanism. This solves the problem of low efficiency of construction personnel using lifting equipment and measuring tape for measurement and marking, and the problem that the lifting equipment is easily restricted by the flatness of the surrounding ground, making it difficult to place the lifting equipment horizontally on the ground.

[0005] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0006] A type of elevation positioning pile for road and bridge construction includes a positioning mechanism for determining the elevation position and an elevation mechanism for performing elevation work. The positioning mechanism includes an arc-shaped arm, with positioning shafts fixedly connected to both ends of the arc-shaped arm, and a support frame fixedly connected to the bottom of the center of the arc-shaped arm.

[0007] The elevation mechanism includes a movable sleeve, a fixed sleeve rod is movably sleeved inside the movable sleeve, a control handle is fixedly connected to the outer wall of the bottom of the movable sleeve, a marking pen is assembled and connected to the outer side of the top of the movable sleeve, and one end of the marking pen is connected to a bridge pier.

[0008] In one possible implementation, the top and bottom of the positioning shaft are both sleeved with a protective sleeve, and the outer wall of the protective sleeve is in contact with the surface of the pier.

[0009] In one possible implementation, both the top and bottom ends of the positioning shaft are fixedly connected to a limiting ball head, and the diameter of the cross-sectional circle of the limiting ball head is larger than the diameter of the cross-sectional circle of the positioning shaft.

[0010] In one possible implementation, a positioning plate is slidably connected inside the support frame, and a support shaft is pin-connected to the top of the positioning plate. A limiting groove is formed inside the support frame, and both ends of the support shaft are slidably connected inside the limiting groove.

[0011] In one possible implementation, a strike plate is fixedly connected to one side of the top of the positioning insert plate, the strike plate is slidably connected inside the support frame, and the angle between the strike plate and the positioning insert plate is an acute angle.

[0012] In one possible implementation, the bottom end of the fixed sleeve is fixedly connected to a limiting plate, and the top end of the limiting plate is in contact with the bottom end of the movable sleeve.

[0013] In one possible implementation, the bottom end of the limiting plate is fixedly connected to a support column, the bottom end of the support column is fixedly connected to a first connecting plate, the top end of the support frame is fixedly connected to a second connecting plate, and the first connecting plate is fixedly connected to the marking pen by bolts.

[0014] In one possible implementation, the fixed sleeve has a storage groove inside, and a scale strip is machined on the inner wall of one side of the storage groove.

[0015] In one possible implementation, the top of the movable sleeve is provided with a cylindrical groove, a support spring is fixedly connected to the inner wall of one end of the cylindrical groove, a connecting block is fixedly connected to one end of the support spring, and the connecting block is movably connected inside the cylindrical groove.

[0016] In one possible implementation, one end of the marking pen is plugged into the interior of a connecting block, and the interior of the connecting block is threaded with a fixing screw, one end of which is in contact with the outer wall of the marking pen.

[0017] The beneficial effects of this application are as follows:

[0018] Firstly, in this scheme, by having the protective sleeve fitted outside the positioning shaft contact the outer wall of the pier, the positioning insert plate is controlled to rotate and unfold around the support shaft at a certain angle, and one end of the positioning insert plate is inserted into the ground. The impact plate is struck with a hammering tool to make the positioning insert plate inserted into the ground. While the support shaft slides inside the limiting groove, it drives the support frame to move to the bottom. When the bottom end of the support frame is flush with the bottom end of the pier and contacts the ground, it is convenient to fix the positioning mechanism to the bottom of the pier and ensure that the axial direction of the second connecting plate is the same as the axial direction of the pier.

[0019] Secondly, in this scheme, the movable sleeve is controlled by the grip to slide directly upwards outside the fixed sleeve. When the movable sleeve moves to the target height outside the fixed sleeve, the movable sleeve is controlled to rotate outside the grip, which drives the marking pen inserted inside the connecting block to form a horizontal marking line on the surface of the pier, thus completing the height marking work required for construction.

[0028] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0029] Example 1:

[0030] This embodiment describes the specific structure of an elevation positioning pile for road and bridge construction, as detailed in the following reference. Figures 1-7 As shown, it includes: a positioning mechanism 2 for determining the elevation position and an elevation mechanism 1 for performing elevation work;

[0031] The positioning mechanism 2 includes an arc-shaped arm 26, with positioning shafts 25 fixedly connected to both ends of the arc-shaped arm 26, and a support frame 22 fixedly connected to the bottom center of the arc-shaped arm 26.

[0032] The top and bottom of the positioning shaft 25 are both sleeved with a protective sleeve 24. After the outer wall of the protective sleeve 24 is made to contact the surface of the pier 3, the positioning mechanism 2 can be positioned vertically downward by the two positioning shafts 25, and the positioning shafts 25 are protected to prevent them from being worn. Only the protective sleeve 24 needs to be replaced.

[0033] Secondly, in order to prevent the sheath 24 from detaching from the positioning shaft 25 during its up-and-down movement, the top and bottom ends of the positioning shaft 25 are fixedly connected to a limiting ball head 28, and the diameter of the cross-sectional circle of the limiting ball head 28 is larger than that of the cross-sectional circle of the positioning shaft 25, so as to block the sheath 24.

[0034] In some examples, the support frame 22 has a sliding connection to a positioning plate 23 inside, and a support shaft 210 is pin-connected to the top of the positioning plate 23 inside. A limit groove 29 is provided inside the support frame 22.

[0035] Among them, the two ends of the support shaft 210 are slidably connected to the inside of the limiting groove 29. When the positioning plate 23 is unfolded around the support shaft 210 and inserted into the ground, the impact plate 21 on the top side of the positioning plate 23 is struck, so that the impact plate 21 is slidably connected to the inside of the support frame 22, which can ensure that the positioning plate 23 sinks into the ground.

[0036] Meanwhile, by setting the angle between the impact plate 21 and the positioning plate 23 to an acute angle, the impact plate 21 can be easily laid flat to provide a striking point for construction workers during the rotation of the positioning plate 23 around the support shaft 210.

[0037] By adopting the above technical solution:

[0038] The above design controls the positioning insert 23 to rotate around the support shaft 210 and unfold to a certain angle by contacting the sheath 24 sleeved on the outside of the positioning shaft 25 with the outer wall of the pier 3, and inserting one end of the positioning insert 23 into the ground. The impact plate 21 is struck by a striking tool to make the positioning insert 23 insert into the ground. While the support shaft 210 slides inside the limiting groove 29, it drives the support frame 22 to move to the bottom. When the bottom end of the support frame 22 is flush with the bottom end of the pier 3 and contacts the ground, the positioning mechanism 2 can be fixed to the bottom of the pier 3 by the triangle formed by the positioning insert 23, the arc arm 26, the positioning shaft 25, the pier 3 and the ground. This makes it easy to assemble the elevation mechanism 1 on the top of the positioning mechanism 2, so that the axial direction of the second connecting plate 27 is the same as the axial direction of the pier 3.

[0039] Example 2:

[0040] Based on Example 1, this example describes the specific structure of the elevation mechanism 1. The elevation mechanism 1 includes a movable sleeve 11, a fixed sleeve rod 13 is movably sleeved inside the movable sleeve 11, a control handle 12 is fixedly connected to the outer wall of the bottom of the movable sleeve 11, a marking pen 17 is assembled and connected to the outer side of the top of the movable sleeve 11, and a bridge pier 3 is contacted at one end of the marking pen 17.

[0041] In order to prevent the bottom end of the movable sleeve 11 from directly contacting the top end of the first connecting plate 15, a limiting plate 14 is fixedly connected to the bottom end of the fixed sleeve rod 13, so that the top end of the limiting plate 14 is in contact with the bottom end of the movable sleeve 11.

[0042] In some examples, the bottom end of the limiting plate 14 is fixedly connected to the support column 16, the bottom end of the support column 16 is fixedly connected to the first connecting plate 15, and the top end of the support frame 22 is fixedly connected to the second connecting plate 27.

[0043] The first connecting plate 15 and the marking pen 17 are fixedly connected by bolts. After the first connecting plate 15 and the marking pen 17 are connected, the fixing sleeve 13 can be mounted on the top of the positioning mechanism 2 so that the elevation mechanism 1 can perform elevation work.

[0044] Secondly, in order to facilitate direct measurement of the height of the mark, a storage groove 112 is provided inside the fixed sleeve 13, and a scale strip 18 is processed on the inner wall of one side of the storage groove 112. The value on the scale strip 18 is determined by the distance between the bottom of the support frame 22 and the limiting plate 14 and the length of the movable sleeve 11.

[0045] In some examples, the top of the movable sleeve 11 has a cylindrical groove 113, and a support spring 19 is fixedly connected to the inner wall of one end of the cylindrical groove 113. A connecting seat block 110 is fixedly connected to one end of the support spring 19.

[0046] Among them, the connecting seat block 110 is movably connected to the inside of the cylindrical groove 113. When the control handle 12 causes the movable sleeve 11 to drive the marking pen 17 to mark on the surface of the pier 3, the support spring 19 can be used to keep one end of the marking pen 17 in contact with the surface of the pier 3.

[0047] Secondly, in order to facilitate the assembly of the marking pen 17 inside the connecting block 110, a fixing screw 111 is threaded inside the connecting block 110. After adjusting the threaded connection between the fixing screw 111 and the connecting block 110, one end of the fixing screw 111 can be made to contact the outer wall of the marking pen 17. By means of the friction between the fixing screw 111 and the surface of the marking pen 17, the marking pen 17 is fixed to the connecting block 110.

[0048] The specific operating steps are as follows:

[0049] S1. By holding the control handle 12, the movable sleeve 11 is controlled to slide straight up outside the fixed sleeve 13, thereby forming a longitudinal marking line on the surface of the pier 3.

[0050] S2. When the movable sleeve 11 moves to the target height outside the fixed sleeve 13, the movable sleeve 11 is controlled to rotate outside the control handle 12, which drives the marking pen 17 inserted inside the connecting seat block 110 to form a horizontal marking line on the surface of the pier 3.

[0051] S3. When the marking pen 17 is used to form a horizontal marking line on the surface of the pier 3, the support spring 19 pushes the connecting seat block 110 to extend out of the inside of the cylindrical groove 113, so that one end of the marking pen 17 is always in contact with the surface of the pier 3.

[0052] By adopting the above technical solution:

[0053] The above design controls the movable sleeve 11 to slide straight up outside the fixed sleeve 13 by holding the control handle 12, thereby forming a longitudinal marking line on the surface of the pier 3, which makes it easier for construction personnel to find the position of the height marking line. When the movable sleeve 11 moves to the target height outside the fixed sleeve 13, the control handle 12 is used to rotate the movable sleeve 11 outside the control handle, which drives the marking pen 17 inserted inside the connecting seat block 110 to form a transverse marking line on the surface of the pier 3, thus completing the height marking work required for construction.

[0054] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
