Description

TECHNICAL FIELD

[0001] The present application relates to the field of concrete pole manufacturing, in particular to a reinforcing bar binding platform for concrete poles. BACKGROUND

[0002] A concrete pole is a hollow cylinder composed of a reinforcing cage framework and concrete pouring and solidification. The reinforcing cage framework of the pole is the basis of the quality of the pole. During production, first, the two ends of multiple horizontal bars are inserted into a disc to form a cylindrical structure, second, the reinforcing bars bent into a spiral shape are sleeved on the outside of the cylinder, then the cylinder is placed horizontally, the discs at both ends of the cylinder are fixed on the binding platform respectively, finally, multiple reinforcing rings are placed in the interior of the cylinder along the length direction of the cylinder to support and shape the cylinder, and the intersections of the spiral reinforcing bars, reinforcing rings and horizontal bars are fixed by manual binding of iron wires, thereby forming a reinforcing cage framework product.

[0003] In current small and medium-sized pole manufacturers, the binding platform is mostly a simple and modified tool clamp, including a support, a fixed jaw and a movable jaw. The fixed jaw and the movable jaw are square steel structures, the two jaws are parallel and pass through the support horizontally, the position of the fixed jaw is unchanged, the distance between the two jaws is adjusted by moving the movable jaw in the support, the distance between the two jaws is shortened to enable the circular ring to be sleeved on the two jaws, and then the movable jaw is moved to increase the distance between the two jaws, the two jaws are in contact with the inner wall of the circular ring from the inside, and the circular ring is clamped on the support. The above structure has two groups and is symmetrically arranged at both ends of the platform on which the reinforcing cage framework is placed, thereby fixing the reinforcing cage framework from both ends.

[0004] The above scheme has the following defects: 1. The two ends of the cylinder are clamped by the fixed jaw, and the movable jaw is in contact with the inner wall of the disc, which can only play a role in preliminary positioning of the cylinder. The fixing firmness is related to the friction between the inner wall of the disc and the contact part of the movable jaw. A very large force is needed to clamp the movable jaw on the cylinder, otherwise the cylinder will shake or rotate when the worker binds the iron wire with multiple points and multiple angles, thereby causing uneven distribution of the reinforcing bars, reinforcing rings and the like on the framework, different strengths of the pole framework at different positions, and non-standard quality of the framework; 2. In order to ensure stable fixation, a worker needs to use a larger force to expand the distance between the two jaws to clamp the reinforcing cage on the two jaws, and a tool needs to be knocked to disassemble the reinforcing cage and then the reinforcing cage is removed, which is time-consuming and labor-intensive. SUMMARY

[0005] The present application provides a reinforcing bar binding platform for concrete poles to solve the problems of unstable positioning of the reinforcing cage by the existing reinforcing bar binding platform and time-consuming and labor-intensive disassembly of the reinforcing cage.

[0006] To solve the above-mentioned purposes, the technical scheme adopted by the present application is as follows: a reinforcing steel bar binding platform for a concrete telegraph pole, comprising a fixed claw, a movable claw and a support, the fixed claw is horizontally fixed in the support, the end of the fixed claw away from the reinforcing cage is provided with a rotatable support rod, the movable claw is located below the fixed claw and is hinged on the support, the movable claw is hollow inside to form an accommodating cavity, the accommodating cavity of the movable claw is filled with hydraulic oil, the accommodating cavity is communicated with an externally-arranged oil supplementing assembly, the end of the movable claw away from the reinforcing cage is slidably connected with a downward pressing plate which can be in contact with the support rod, a first spring is arranged between the lower surface of the downward pressing plate and the bottom surface of the accommodating cavity, the contact part of the movable claw and the reinforcing cage disc is provided with a through hole penetrating through the inner wall of the movable claw, a first sliding block is slidably and sealingly connected in the through hole, the head of the first sliding block is clamped with a rotatable ball, and a second spring is connected between the bottom of the first sliding block and the through hole.

[0007] The basic principle of the present scheme is that when the reinforcing cage clamped on the two claws needs to be removed, the support rod is rotated clockwise and abuts against the downward pressing plate, the downward pressing plate slides downward and extrudes the hydraulic oil in the accommodating cavity, the hydraulic oil drives the first sliding block in the through hole to move towards the surface of the disc, the ball at the head of the first sliding block is in point contact with the disc, the support rod continues to rotate to drive the movable claw to rotate clockwise, the distance between the movable claw and the fixed claw is reduced, and the reinforcing cage can be removed.

[0008] The present scheme has the following beneficial effects:

[0009] 1. In the prior art, the staff needs to manually adjust the movable claw every time a new reinforcing cage framework is bound, in order to firmly clamp the reinforcing cage on the movable claw, the staff needs to exert a great force for fixation, and the friction force between the disc and the movable claw is also very large when disassembling, which is inconvenient for assembly and disassembly, the present scheme utilizes the principle of lever to adjust the angle of the movable claw by rotating the support rod, and the structure is simple.

[0010] 2. When the movable claw rotates, the friction force between the disc and the contact part of the movable claw is large, the present scheme opens a through hole at the contact part, and a first sliding block is slidably connected in the through hole, when the downward pressing plate on the movable claw is abutted, the hydraulic oil pushes the first sliding block out, so that the ball is in point contact with the contact part of the disc, and the disc and the movable claw are more easily separated by rotating the ball.

[0011] Further, a first oil channel penetrating through the first sliding block and communicated to the surface of the ball is opened in the inside of the first sliding block. The oil channel is arranged to enable the surface of the ball to adhere to the hydraulic oil, which is more conducive to the rotation of the ball.

[0012] Further, the first sliding block is internally provided with a second oil channel communicating with the accommodating cavity, the second oil channel and the first oil channel are communicated through a third oil channel, one end of the third oil channel extends to the side wall of the first sliding block, one end of the third oil channel close to the side wall of the first sliding block is slidingly connected with a plug, one end of the third oil channel close to the bottom is slidingly connected with a second sliding block through a third spring, the second sliding block is connected with the plug through a rod, and the second sliding block is internally provided with a second one-way valve allowing liquid to flow from the bottom of the third oil channel to the opening of the third oil channel only. While the balls are sliding out, the movable claw rotates, the distance between the balls and the disc is reduced, the hydraulic oil is introduced into the second oil channel to prevent the balls from being crushed, after the plug is pushed by the hydraulic oil, the plug is attached to the inner wall of the through hole to prevent the first sliding block from continuously sliding out, and the second sliding block of the first oil channel is separated downward, the surface of the ball is communicated with the hydraulic oil, when the third spring drives the second sliding block to reset, the third channel where the third spring is located has part of the hydraulic oil, and the second sliding block discharges the part of the hydraulic oil through the second one-way valve.

[0013] Further, the oil supplement assembly comprises a hydraulic oil tank capable of being extruded and deformed and an oil supplement channel formed in the support, the hydraulic oil tank is located in the support below the movable claw, one end of the oil supplement channel is connected with the hydraulic oil tank, the other end of the oil supplement channel extends to the surface of the movable claw, and the lower surface of the movable claw is provided with a first one-way valve allowing liquid to flow into the accommodating cavity from the outside only. Since the surface of the ball is attached with the hydraulic oil, the hydraulic oil in the accommodating cavity is consumed, and the oil supplement assembly is used to supplement the hydraulic oil.

[0014] Further, the fixed claw is in interference fit with the support in width. The fixed claw is fixed firmly in the support, and the fixed claw can be replaced after wear.

[0015] Further, the support rod is driven to rotate through the motor, and the rotation center key of the support rod is connected with the output shaft of the motor. The motor is used to drive the support rod to rotate, and manpower is saved.

[0016] Further, the lower pressing plate at the tail end of the movable claw is in the shape of an inclined block. The inclined block is used for transition to ensure that the support rod can be attached to the movable claw when the support rod rotates.

[0017] Further, the through hole is sequentially provided with a plurality of holes along the height of the movable claw. The plurality of through holes are used to make the movable claw and the disc have a plurality of points of rolling contact, and the movable claw is smoothly rotated.

[0018] Further, the first oil channel, the ball and the through hole are coaxially arranged. The coaxial arrangement makes the ball and the oil channel have the shortest distance, and the hydraulic oil consumption is reduced.

[0019] Further, one end of the lower pressing block away from the steel wire cage is rounded. The rounded corner is used for smooth attachment of the support rod and the lower pressing plate. DETAILED DESCRIPTION

[0020] Figure 1 The drawings are schematic views of embodiments of the present application.

[0021] Figure 2 This is the structure of the through hole 6 in an embodiment of the present invention. Detailed Implementation

[0022] The following detailed description illustrates the specific implementation method:

[0023] The reference numerals in the accompanying drawings include: bracket 1, hydraulic oil tank 11, fluid replenishment channel 12, fixed claw 2, movable claw 3, hinge point 31, lower pressure plate 32, support rod 4, receiving cavity 5, first spring 51, first check valve 52, through hole 6, first slider 7, first oil passage 71, second oil passage 72, third oil passage 73, second spring 74, second slider 801, block 802, third spring 803, second check valve 804, ball bearing 9, disc 101, horizontal rib 102, reinforcing rib 103, reinforcing ring 104.

[0024] The through hole 6 is located on the right side of the lower pressure plate 32, and this direction is used as a reference.

[0025] The basic implementation examples are as follows: Figure 1 To be continued Figure 2 As shown:

[0026] The horizontal utility pole's reinforcing cage is fixed at both ends to support 1. Supports 1 are symmetrically arranged at both ends of the reinforcing cage, such as... Figure 1 The structure of the right end of the bundling platform in this embodiment is shown. The following description will take the right end structure as an example. The bracket 1 is placed on a horizontal platform. The bracket 1 has a first mounting hole and a second mounting hole that are horizontally through the bracket 1 from top to bottom. The first mounting hole is internally fitted with a horizontal fixed claw 2, and the second mounting hole is internally hinged with a horizontal movable claw 3. The fixed claw 2 and the movable claw 3 are "L" shaped rods. The fixed plate at the end of the steel cage is engaged through the bend of the fixed claw 2 and the movable claw 3.

[0027] A support rod 4 is rotatably connected to the horizontal section of the fixed claw 2 along the length of the horizontal section. The output shaft of the motor is keyed at the rotation center of the support rod 4, and the motor can drive the support rod 4 to rotate clockwise.

[0028] The movable claw 3 has a cavity 5 machined inside, which is filled with hydraulic oil. The horizontal section on the right side of the hinge of the movable claw 3 is slidably connected to the lower pressure plate 32. The side wall of the lower pressure plate 32 is sealed to the part that contacts the movable claw 3. The bottom surface of the lower pressure plate 32 is fixed between the bottom surface of the lower pressure plate 32 and the upper surface of the cavity 5 below it. The upper surface of the lower pressure plate 32 is an inclined surface with a gradually decreasing height from left to right. When the support rod 4 rotates clockwise, the distance between the inclined surface and the support rod 4 gradually shrinks. The support rod 4 pushes the lower pressure plate 32 to move downward. After the bottom surface of the lower pressure plate 32 contacts the cavity 5, in order to ensure the smooth rotation of the support rod 4, the movable claw 3 is pushed by the support rod 4, and the entire movable claw 3 rotates clockwise along its hinge.

[0029] The movable claw 3 is in contact with the side wall of the fixed disc, and a through hole 6 penetrating the side wall horizontally is formed in the side wall. In the embodiment, the number of the through holes 6 is three, and the through holes 6 are arranged in sequence from top to bottom along the contact part. Figure 2 As shown in the figure, the first sliding block 7 is slidably connected inside the through hole 6, the second spring 74 is fixed between the first sliding block 7 and the bottom surface of the through hole 6, the first sliding block 7 is rotatably connected to the ball 9 at one end close to the opening of the through hole 6, the first sliding block 7 has a horizontal first oil channel 71 and a second oil channel 72 inside, the first oil channel 71 and the second oil channel 72 are both communicated with the containing cavity 5, the width of the second oil channel 72 is wider than that of the first oil channel 71, so that the flow of the second oil channel 72 is greater than that of the first oil channel 71. The first oil channel 71 and the second oil channel 72 are communicated through a vertical third oil channel 73, the other end of the first oil channel 71 is communicated to the surface of the ball 9, the third oil channel 73 is a blind hole and its other end penetrates the side wall of the first sliding block 7, the third oil channel 73 has a plug 802 slidably connected at one end close to the opening, the third oil channel 73 has a second sliding block 801 slidably connected at one end close to the bottom, and the second sliding block 801 and the bottom of the blind hole are fixed with a third spring 803, the second sliding block 801 and the plug 802 are connected by a rod, and the second sliding block 801 has a second one-way valve 804 installed inside, which only allows the liquid in the blind hole of the third oil channel 73 to flow out of the opening of the third oil channel 73. When the third spring 803 is in a natural state, the second sliding block 801 blocks the first oil channel 71, the plug 802 seals the opening of the third oil channel 73, and the maximum displacement of the second sliding block 801 in the third oil channel 73 does not block the second oil channel 72.

[0030] When the hydraulic oil enters the through hole 6, it pushes the first sliding block 7 to slide to the right, and at the same time, the hydraulic oil enters the first oil channel 71 and the second oil channel 72. As the hydraulic oil pressure increases, the plug 802 is pushed by the hydraulic oil and adheres to the inner wall of the through hole 6, so that the friction between the first sliding block 7 and the through hole 6 increases, and the first sliding block 7 stops sliding to the right. The ball 9 adheres to the side wall of the support 1, avoiding the ball 9 from moving forward under the sliding of the first sliding block 7, preventing the ball 9 from being crushed due to excessive extrusion force, and at the same time, the movement of the plug 802 drives the second sliding block 801 to slide downward. The hydraulic oil is conducted in the first oil channel 71 and flows to the surface of the ball 9, and the ball 9 rotates more smoothly.

[0031] The first one-way valve 52 is installed on the bottom surface of the movable claw 3, and when the movable claw 3 is in a horizontal state, the first one-way valve 52 adheres to the support 1. The support 1 has a liquid supplement channel corresponding to the first one-way valve 52, and the liquid can only flow from the liquid supplement channel into the containing cavity 5. The lower end of the liquid supplement channel is connected to the hydraulic oil tank 11, and the shell of the hydraulic oil tank 11 is a manually squeezed bottle. After the steel wire cage with a binding is put in each time, the staff can squeeze the hydraulic oil tank 11 to supplement the hydraulic oil into the containing cavity 5 of the movable claw 3.

[0032] The implementation process is as follows:

[0033] When the reinforcement cage is fixedly installed on the support 1, the movable claw 3 is inclined so that the distance between the movable claw 3 and the first end of the fixed claw 2 is short. After the disc 101 of the reinforcement cage is sleeved, the entire reinforcement cage is straightened, the staff can install the reinforcing ring 104 and the spiral reinforcing bar 103 on the reinforcement cage, and the supporting ring and the reinforcing bar 103 are fixed on the wire cage by bundling steel wires at the intersection points.

[0034] After the wire pole overall wire cage framework is completed, the motor is started to rotate the supporting rod 4 clockwise, the lower end of the supporting rod 4 abuts against the lower pressing plate 32, the lower pressing plate 32 moves downward, and the entire movable claw 3 rotates clockwise. As the rotation angle of the supporting rod 4 gradually increases, the displacement of the lower pressing plate 32 sliding downward increases, and the pressure of the hydraulic oil in the containing cavity 5 also gradually increases. The hydraulic oil flows to the through hole 6 on the movable claw 3 and pushes the first sliding block 7 to move outward from the through hole 6, and at the same time, the second sliding block 801 and the block 802 move to the side wall of the through hole 6. While the ball 9 is in contact with the side wall of the disc 101 to rotate, the block 802 is in contact with the side wall of the through hole 6 to fix the first sliding block 7. After the second sliding block 801 moves downward, the first oil channel 71 is connected, the hydraulic oil flows onto the surface of the ball 9, and the lubricating effect is achieved. When the movable claw 3 rotates to the maximum angle, the motor stops rotating the supporting rod 4, and the disc 101 of the wire cage can be separated from the clamping of the movable claw 3 and the fixed claw 2, and the staff can take down the completed wire cage.

[0035] The new wire cage to be made is installed again, the motor rotates clockwise again, and the supporting rod 4 continues to rotate clockwise from the position where it was stopped. Since the distance between the supporting rod 4 and the movable claw 3 decreases, the lower pressing plate 32 rebounds under the action of the first spring 51, and the hydraulic oil leaves the surface of the block 802. Under the contraction action of the third spring 803, the hydraulic oil at the upper end of the second sliding block 801 is discharged along the second one-way valve 804, the second sliding block 801 pulls the block 802 to move upward, and the friction force between the first sliding block 7 and the through hole 6 decreases. Under the contraction action of the second spring 74, the first sliding block 7 moves to the bottom of the through hole 6, the ball 9 leaves the surface of the support 1, the movable claw 3 gradually rotates counterclockwise to a horizontal state, clamps and fixes the wire cage, and the staff can start the bundling work. When hydraulic oil needs to be supplemented, manually squeeze the hydraulic oil tank 11, and the hydraulic oil flows into the containing cavity 5 of the movable claw 3 through the supplementing pipeline and the first one-way valve 52.

[0036] The above-mentioned are only embodiments of the present application, and the common knowledge of specific structures and characteristics in the scheme is not described too much. It should be pointed out that for those skilled in the art, without departing from the structure of the present application, a number of modifications and improvements can be made, which should also be considered as the protection scope of the present application, which will not affect the effect and practicality of the patent. The protection scope claimed in this application should be subject to the content of its claims, and the specific implementation mode and the like recorded in the specification can be used to explain the content of the claims.
