Description

Technical Field

[0001] The present invention relates to the technical field of positioning and installation of protective fence columns, and specifically to a positioning and installation bench for concrete protective fence columns. Background Art

[0002] As an important building and municipal facility, concrete protective fences play a crucial role in safety protection in areas such as roads, bridges, and around buildings. These fences not only require excellent durability and stability but also need to ensure precise positioning during installation to guarantee the stability and safety of their overall structure.

[0003] According to a positioning and installation bench for concrete protective fence columns with the publication number "CN109138608B" disclosed on the Chinese Patent Network, by adjusting the adjusting screw and observing the level, the overall bench can be adjusted to be on a horizontal plane. Then, the column is hoisted in, and the fixing screw on the fixing clamp is adjusted to fix the column on the bench and keep it vertical. By adjusting the horizontal adjusting screw and the longitudinal adjusting screw, the transverse moving frame can be moved horizontally and longitudinally. There is a column fixing clamp on the transverse moving frame, which can make the column move along with the displacement of the transverse moving frame, thereby accurately positioning the column. Finally, the foundation concrete of the column is poured, reducing the time required for column positioning and fixing, with simple operation and improving the installation quality of the protective fence.

[0004] Although the above patent solves the problems of slow construction speed and difficult fixation in the main method of using an artificial spirit level for positioning, during the construction process, if the installation equipment is affected by external factors such as loose soil and uneven ground, the equipment will tilt, resulting in deviation in the vertical positioning of the already fixed column, making the column unable to be accurately installed perpendicular to the ground, thus weakening the stability and protective ability of the fence. Summary of the Invention

[0005] The purpose of the present invention is to provide a positioning and installation bench for concrete protective fence columns to solve the problem in the prior art that the tilt of the installation equipment causes deviation in the vertical positioning of the column, affecting the stability and protective ability of the fence as mentioned in the above background art.

[0006] To achieve the above object, the present invention provides the following technical solution: A positioning and installation bench for concrete protection fence columns, including a collar. A first cavity is opened inside the collar. A bracket is provided below the collar, and a second cavity is opened inside the bracket. It further includes a clamping component for clamping the columns. The clamping component includes multiple groups of driving teeth arranged at equal intervals inside the first cavity and rotatably connected to the inner wall of the first cavity. One end of any group of driving teeth is fixedly connected to a driving source. The surfaces of each group of driving teeth are meshed with two groups of racks distributed vertically. One side of the two racks on the same side is interconnected with a piston rod, and the piston rods are at the same height. The ends of the two piston rods are movably connected to clamping plates.

[0007] Further, multiple groups of guide grooves are opened on the bottom surface of the second cavity, multiple groups of limit grooves are opened on one side of the second cavity, and multiple groups of notches are opened on the top surface of the second cavity.

[0008] Further, every two groups of adjacent racks are connected by a flexible belt. The inner arc surface of each flexible belt is attached to a guide roller, and the guide roller is rotatably connected to the bottom surface of the first cavity.

[0009] Further, one ends of the two piston rods on the same side are both communicated with an elastic hose, and the lower ends of the two elastic hoses are fixedly installed on the upper surface of the bracket.

[0010] Further, it further includes a balance component for ensuring that the column can always be in a balanced position. The balance component includes multiple groups of telescopic rods installed at equal intervals on the upper surface of the bracket and a moving plate arranged inside the second cavity. Multiple groups of straight grooves are opened inside the moving plate, a sliding groove is opened on the upper surface of the moving plate, an elastic head is slidably connected inside the sliding groove, a guide rod is inserted inside the straight groove, and the ends of the two guide rods on the same side are both fixedly connected to the same group of connecting plates, and the connecting plates are slidably matched with the limit grooves through sliders.

[0011] Further, a ball is fixedly installed at the upper end of the telescopic rod, and the ball is movably connected to the lower surface of the collar. The lower end of the telescopic rod is communicated with an air inlet pipe, the air inlet pipe is communicated with two groups of delivery pipes, and the delivery pipes are communicated with the elastic hoses.

[0012] Further, the moving plate has an L-shaped structure. A matching block is fixedly installed at the lower end of the moving plate, and the matching block is arranged inside the guide groove and is slidably matched with it.

[0013] Further, the elastic head is initially arranged inside the notch and is clamped and matched with the notch. An exhaust hole communicating with the outside is opened at the upper end of the elastic head.

[0014] Furthermore, the guide rod is inserted into the straight groove at two-thirds of its interior position, and the guide rod is elastically connected to the inner wall of the straight groove through a connecting spring.

[0015] The technical solution provided by the present invention has the following beneficial effects compared with the known prior art:

[0016] 1. Through the mutually cooperating components such as the driving teeth, flexible belt, and clamping plate provided by the present invention, when installing the column, the driving source is started, which drives one set of driving teeth fixedly connected to the driving source to start rotating, driving the racks distributed up and down to move relatively. At the same time, with the cooperation of the flexible belt and the guide rollers, multiple racks can move synchronously. The moving racks will drive the piston rod to start rotating and push the clamping plate to start extending, coming into contact with the column. And with the continuous movement of the racks, the piston rod is compressed, thus achieving stable clamping of the column and ensuring the stability of the column during the installation process.

[0017] 2. Through the mutually cooperating components such as the telescopic rod, elastic head, and connecting plate provided by the present invention, when the column is fixed, the gas inside the compressed piston rod will enter the interior of the elastic hose. When the bracket tilts, the two moving plates located in the tilting direction will slide inside the guide groove, and at the same time, the elastic head will move out of the notch, enabling the flattened conveying pipe to recover. And the gas inside the elastic hose is introduced into the telescopic rod, jacking up one side of the tilted collar, so that the collar maintains a balanced state, thereby ensuring the installation accuracy of the column and the stability and protection ability of the fence.

Detailed implementation manners

[0030] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] The present invention will be further described below with reference to the embodiments.

[0032] Embodiment: A positioning and installation bench for the column of a concrete protection fence, as Figures 1 - 10 shown, includes a collar 1. By providing the collar 1, it is convenient for the column to pass through its interior; a first cavity 101 is provided inside the collar 1, and a bracket 2 is provided below the collar 1, and a second cavity 201 is provided inside the bracket 2. By providing the bracket 2, it can then contact the ground to achieve the purpose of support; it should be noted that adjustable legs can be installed at the lower end of the bracket 2 to adjust different heights according to columns of different lengths;

[0033] Among them, a plurality of groups of guide grooves 202 are formed in the bottom surface of the second cavity 201, and a plurality of groups of limiting grooves 203 are formed in one side of the second cavity 201. By forming the guide grooves 202 and the limiting grooves 203, the guiding and limiting functions can be achieved. It should be noted that, in combination with the attached Figure 6 , the guide groove 202 is formed by combining a set of horizontal grooves and a set of vertical grooves in communication, forming a state of two short strokes and two long strokes; a plurality of groups of notches 204 are formed in the top surface of the second cavity 201. By providing the notches 204, clamping with other components can be achieved to realize the positioning purpose.

[0034] In combination with the attached Figure 1 - attached Figure 10 , it further includes a clamping assembly 3 for clamping the upright column, so that the upright column can be kept stable during the installation process, and the positioning of the upright column in the vertical direction will not deviate; the clamping assembly 3 includes a plurality of groups of driving teeth 301 that are equidistantly arranged inside the first cavity 101 and rotatably connected to the inner wall of the first cavity 101. By providing the driving teeth 301, the function of kinetic energy transmission can be achieved to drive the components to act; one end of any group of driving teeth 301 is fixedly connected to a driving source, and the driving source is a prior art and is not shown in the figure. It should be noted that the driving source can be selected as a device with a self-locking function such as a driving motor; two groups of racks 302 distributed up and down are meshed on the surface of each group of driving teeth 301. By providing the racks 302, the racks 302 can cooperate with the driving teeth 301 to achieve the purpose of lateral movement. It should be noted that the two groups of racks 302 move relatively and do not move in the same direction.

[0035] Among them, every two groups of adjacent racks 302 are connected by a flexible belt 303. By setting the flexible belt 303, it can play a connecting role, so that multiple groups of racks 302 located above and below are connected, achieving the purpose of synchronous movement; the inner arc surface of each flexible belt 303 is attached with a guide roller 3031, and the guide roller 3031 is rotatably connected to the bottom surface of the first cavity 101. By setting the guide roller 3031, it can play a guiding role and ensure that multiple groups of racks 302 can move normally; on one side of two racks 302 on the same side, a piston rod 304 is interactively connected, and the piston rods 304 are at the same height. By setting the piston rod 304, it can move synchronously with the rack 302; one end of two piston rods 304 on the same side is communicated with an elastic hose 3041, and the lower ends of the two elastic hoses 3041 are fixedly installed on the upper surface of the bracket 2. By setting the elastic hose 3041, it can play a role in storing and transporting gas; the ends of the two piston rods 304 are movably connected with a clamping plate 305. By setting the clamping plate 305, it can extend out of the inside of the collar 1 under the action of the piston rod 304 and contact the surface of the column, achieving the purpose of clamping the column; it should be noted that one side of the clamping plate 305 close to the driving tooth 301 is fixedly connected to the inner wall of the first cavity 101 through a telescopic connecting rod (prior art, not shown in the figure due to perspective reasons) to ensure that the clamping plate 305 can extend normally under the action of the piston rod 304.

[0036] Combined with the attached Figure 1 - attached Figure 10 It also includes a balance component 4 for ensuring that the column can always be in a balanced position. When the installation bench tilts, it can still lift the synchronously tilted collar 1, so that the collar 1 can still maintain a balanced state, thereby ensuring that the positioning of the column in the vertical direction will not deviate and ensuring the installation accuracy; the balance component 4 includes multiple groups of telescopic rods 401 equidistantly installed on the upper surface of the bracket 2. By setting the telescopic rods 401, it can play a connecting and supporting role; the upper end of the telescopic rod 401 is fixedly installed with a ball 4011, and the ball 4011 is movably connected to the lower surface of the collar 1. By setting the ball 4011, it is convenient for the collar 1 to rotate after the installation bench deviates, achieving the purpose of maintaining balance.

[0037] Among them, an air inlet pipe 4012 is connected to the lower end of the telescopic rod 401. The air inlet pipe 4012 is connected to two groups of delivery pipes 4013, and the delivery pipes 4013 are connected to the elastic hose 3041. By providing the air inlet pipe 4012 and the delivery pipes 4013, the function of gas transmission can be achieved, enabling gas to enter the interior of the telescopic rod 401 and jack up the collar 1 movably connected to the ball 4011; and a moving plate 402 provided inside the second cavity 201. By providing the moving plate 402, its movement can drive other components to act synchronously to achieve inflation and deflation of the telescopic rod 401.

[0038] Among them, a plurality of straight grooves 4021 are formed inside the moving plate 402. By providing the straight grooves 4021, the functions of guiding and limiting can be achieved; the moving plate 402 has an L-shaped structure. A fitting block 405 is fixedly installed at the lower end of the moving plate 402, and the fitting block 405 is arranged inside the guide groove 202 and is in sliding fit with it. By providing the fitting block 405, the functions of guiding and limiting can be achieved to ensure that the moving plate 402 can move along a fixed track; it should be noted that the fitting block 405 is initially arranged at the intersection of the horizontal groove and the vertical groove. When the fitting block 405 moves towards the inside of the two short strokes, it means that the surface mounting bracket tilts towards one side of the short stroke. If it moves towards the inside of the long stroke, the mounting bracket will tilt towards the long stroke direction; a chute 403 is formed on the upper surface of the moving plate 402. By providing the chute 403, the functions of guiding and limiting can be achieved.

[0039] Among them, an elastic head 404 is slidably connected inside the chute 403. The elastic head 404 is initially arranged inside the notch 204 and is in snap fit with the notch 204. An exhaust hole communicating with the outside is formed at the upper end of the elastic head 404. By providing the elastic head 404, the inflation and deflation of the telescopic rod 401 can be controlled; it should be noted that the elastic head 404 is initially arranged inside the notch 204, and the exhaust hole formed at the upper end is connected to the telescopic rod 401 through the air inlet pipe 4012, and will squeeze the delivery pipe 4013 arranged inside the notch 204, causing the delivery pipe 4013 to change from the normal state to a flat state (i.e., the inner walls of the delivery pipe 4013 are in contact), stopping the gas delivery. When the fitting block 405 moves towards the inside of the two short strokes, that is, the surface mounting bracket tilts towards one side of the short stroke, the moving plate 402 will drive the elastic head 404 to move out of the notch 204 and contract. If it moves towards the inside of the long stroke, the mounting bracket will tilt towards the long stroke direction, and the moving plate 402 will not drive the elastic head 404 to move out of the notch 204, but only allow the elastic head 404 to slide inside the straight groove 4021.

[0040] Among them, a guide rod 406 is inserted inside the straight groove 4021. The guide rod 406 is inserted at two-thirds of the position inside the straight groove 4021, and the guide rod 406 is elastically connected to the inner wall of the straight groove 4021 through a connecting spring. By setting the guide rod 406, it can play a guiding and limiting role; at the same time, by setting the connecting spring, it can drive the moving plate 402 after moving to reset through the reaction force generated by its deformation; it should be noted that by inserting the guide rod 406 at two-thirds of the position inside the straight groove 4021, it is convenient for the moving plate 402 to move towards the inclined side, thereby driving the elastic head 404 to move out of the notch 204, so that the delivery pipe 4013 can return to its original state and inflate the inside of the telescopic rod 401; the ends of the two groups of guide rods 406 on the same side are fixedly connected to the same group of connecting plates 407, and the connecting plates 407 are slidably matched with the limiting grooves 203 through sliders. By setting the connecting plates 407, it can play a guiding and limiting role.

[0041] Specifically, when installing the column, first lift the column to be installed and pass it through the inside of the collar 1, and then start the drive source, so that the operating drive source drives one of the drive gears 301 fixedly connected to it to start rotating, thereby driving the racks 302 distributed up and down to move relative to each other, and with the cooperation of the flexible belt 303 and the guide roller 3031, multiple groups of racks 302 located above and below can move synchronously;

[0042] The moving rack 302 will drive the piston rod 304 to start rotating and push the clamping plate 305 to start extending to contact the column, and with the continuous movement of the rack 302, it will start to compress the piston rod 304, thereby realizing stable clamping of the column and ensuring the stability of the column during the installation process;

[0043] When the column is fixed, the gas inside the compressed piston rod 304 will enter the inside of the elastic hose 3041. Then, when the bracket 2 is tilted under the influence of the external environment, the two groups of moving plates 402 located in the inclined direction will slide inside the guide grooves 202, so that the inner wall of the straight groove 4021 starts to contact the end of the guide rod 406. At the same time, the moving moving plate 402 will drive the elastic head 404 to move out of the notch 204, so that the flattened delivery pipe 4013 can be restored, and the gas inside the elastic hose 3041 is introduced into the inside of the telescopic rod 401, pushing up the upper end of the telescopic rod 401, thereby pushing up one side of the tilted collar 1, so that the collar 1 maintains a balanced state, thereby ensuring the installation accuracy of the column and the stability and protection ability of the fence.

[0044] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
