Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of positioning devices, and in particular to a precise positioning device for lattice columns. Background Art
[0002] As a compression-bending member, lattice columns are widely used to enclose foundation pits and support them to maintain stability. As the load-bearing structure of the internal support system, if the verticality and position deviation of the lattice column are too large, it will surely cause eccentric compression of the lattice column member and pose a safety hazard to the support structure.
[0003] In order to ensure the verticality and accurate center point position of the lattice column, the existing conventional method is to directly position the lattice column by using its own gravity when hoisting and placing the lattice column, setting a cross reference line and combining it with a plumb bob, and then placing the lattice column into the casing. The verticality of the lattice column and the position of the center point of the lattice column are controlled. However, when the distance between the top of the lattice column and the construction site ground surface is too large, due to insufficient visibility, it may be difficult to ensure the alignment of the reference line of the lattice column and the reference line, resulting in the lattice column tilting and shaking during the lowering process, causing deviation in the center point positioning and verticality, and affecting the construction safety of the foundation pit steel support and capping beam. Summary of the Invention
[0004] The present invention provides a precise positioning device for lattice columns to solve the problems that the lattice column tilts and deviates during the lowering process, resulting in deviation in the center point positioning and verticality, and affecting the construction safety of the foundation pit steel support and capping beam.
[0005] To achieve the above object, the present invention adopts the following technical solution: A precise positioning device for lattice columns includes a lattice column body. A casing is provided on one side of the lattice column body, and the casing is sleeved on the surface of the lattice column body. A limiting device is provided on one side of the lattice column body. The limiting device includes a rectangular frame. A connecting device is provided between the rectangular frame and the casing. The rectangular frame is sleeved on the surface of the lattice column body. Four sleeves are symmetrically and fixedly connected to the surface of the rectangular frame. The inner walls of the four sleeves are all rotatably connected with first screws. Threaded hole plates are threadedly connected to the surfaces of the four first screws. One side of the four threaded hole plates close to the rectangular frame is fixedly connected with scale rods. The surfaces of the four scale rods are all slidably connected to the inner wall of the rectangular frame. The four scale rods are all arranged inside the rectangular frame. The adjacent ends of the four scale rods are all fixedly connected with positioning plates. The four positioning plates are all arranged inside the rectangular frame.
[0006] The effects achieved by the above components are as follows: By setting the limiting device, first bury the casing into the ground and find the central position inside the casing through a measuring tool. At the same time, quickly assemble the limiting device with the casing through the connecting device, so that the central position of the rectangular frame corresponds to the central position of the casing. At this time, use an external lifting device to hoist and move the lattice column body. When the lattice column body moves to the surface and enters the position inside the rectangular frame, stop moving the lattice column body, so that part of the lattice column body is located in the middle of the four positioning plates. At this time, manually rotate the four first screws, so that the four first screws rotate along the inside of the four sleeves respectively. Under the threaded connection of the first screw and the screw hole plate, the four first screws drive the four screw hole rods to move left and right along their surfaces through rotation, so that the four screw hole plates drive the four scale rods to move closer to each other inside the rectangular frame, so that the four scale rods drive the four positioning plates to move closer to each other inside the rectangular frame. At this time, the operator can observe the corresponding positions of the scales on the four scale rods and the rectangular frame to achieve precise adjustment of the moving positions of the four scale rods, so that the four positioning plates can move precisely under the action of the four scale rods and the four positioning plates can be adjusted to an equal distance position, so that the central positions of the four positioning plates correspond to the central position inside the casing. When the four positioning plates move to the position where they are simultaneously in contact with the surface of the lattice column body inside the rectangular frame, the four positioning plates intercept the lattice column body inside the rectangular frame, thereby achieving rapid positioning of the lattice column body. At this time, continue to lower the lattice column body through the transmission of the lifting device, so that the lattice column body moves into the casing and is intercepted and limited by the four positioning plates during the movement, completing the rapid positioning effect during the installation of the lattice column body, reducing the inclination and shaking of the lattice column body when it is placed inside the casing, resulting in a deviation between the central position of the lattice column body and the central point position of the casing, and reducing the installation quality of the lattice column body, which affects the construction safety of the foundation pit steel strut and the capping beam.

[0008] The effects achieved by the above components are as follows: By setting the positioning rod and the sliding rail, first manually move the positioning rod so that the positioning rod moves up and down inside the sliding rail. When the positioning rod moves to an appropriate position inside the casing, the inner wall of the circular hole coincides with the inner wall of any hole on the positioning rod. At this time, turn the bolt with a tool so that the bolt turns into any hole of the circular hole and the positioning rod to fix the position of the positioning rod, so that the positioning rod enters the casing and cooperates with the sliding rail to assist in intercepting the lattice column body during the movement process, increasing the interception length of the lattice column body, reducing the short-term shaking when the lattice column body moves out of the limiting range of the positioning plate, and preventing the situation that the lattice column body generates a position deviation at the moment of leaving the rectangular frame and entering the casing, which affects the positioning effect, and further improving the limiting effect on the lattice column body.

At the same time, under the rotation of the rollers, the lattice column body can reduce the wear on the surface of the positioning plates during the movement into the casing, reducing the situation that the surface of the positioning rod is severely worn due to long-term contact with the surface of the lattice column body, which affects the positioning accuracy, and improving the service life and efficiency of the positioning plates.

One side of the connecting block is fixedly connected with a dual-axis motor, and both output ends of the dual-axis motor are fixedly connected with second screws. Threaded cylinders are threadedly connected to the surfaces of the two second screws. One side of each of the two threaded cylinders is fixedly connected with a clamping plate, and the surface of the clamping plate is arc-shaped.
[0016] The effects achieved by the above components are as follows: By setting the connecting device, first manually move the rectangular frame, so that the rectangular frame drives the connecting block to move, the connecting block drives the dual-axis motor to move, the dual-axis motor drives the two second screws to move, the two second screws drive the two threaded cylinders to move, and the two threaded cylinders drive the two clamping plates to move. When the rectangular frame moves to a position where it fits the surface of the opening of the protective cylinder, the protective cylinder is located between the two clamping plates. At this time, start the dual-axis motor, so that the dual-axis motor drives the two second screws to rotate, the two second screws drive the two threaded cylinders to move towards each other, and the two threaded cylinders drive the two clamping plates to move towards each other. When the two clamping plates move to a position where they simultaneously squeeze the surface of the protective cylinder, the rectangular frame is connected and fixed to the protective cylinder under the clamping action of the two clamping plates on the surface of the protective cylinder, thus completing the rapid assembly of the limiting device and the protective cylinder, enabling personnel to quickly disassemble it after the limiting device is used, facilitating the repeated use of the limiting device, reducing material waste, and at the same time increasing the flexibility of use of the limiting device, enabling the limiting device to be adapted to protective cylinders of different sizes for use, and improving the use efficiency and practicality of the limiting device.

[0018] The effects achieved by the above components are as follows: By setting the top blocks, the plurality of top blocks can improve the clamping efficiency of the clamping plates, reduce the situation of sliding when the clamping plates squeeze the surface of the protective cylinder, and at the same time, under the action of the plurality of top blocks, the force application points of the clamping plates can be increased, enabling the clamping plates to still achieve the clamping effect when clamping a relatively small protective cylinder.
[0019] Preferably, a plurality of reinforcing ribs are fixedly connected to one side of each of the two clamping plates. The plurality of reinforcing ribs are arranged at equal distances.

[0023] Preferably, two circular hole plates are symmetrically and fixedly connected to one end of the rectangular frame close to the dual-axis motor, and the two circular hole plates are respectively sleeved on the surfaces of the two second screws.
[0024] The effects achieved by the above components are as follows: By setting the circular hole plates, the circular hole plates can assist in limiting and supporting the second screw, reducing the situation that the second screw shakes up and down during use, affecting the use effect, improving the use stability of the second screw, and at the same time preventing the threaded cylinder from colliding with the surface of the dual-axis motor when moving left and right along the surface of the second screw.
[0025] In summary, the beneficial effects of the present invention are as follows: By setting the limiting device, the center positions of the lattice column body and the casing can be quickly positioned, and at the same time, the limiting effect on the moving lattice column body can be always maintained, reducing the situation that the lattice column body tilts and shakes when being placed inside the casing, resulting in a deviation between the center position of the lattice column body and the center point position of the casing, and reducing the installation quality of the lattice column body, affecting the construction safety of the foundation pit steel strut and the coping beam.

Detailed implementation manners
[0029] Refer to Figures 1-6As shown in the figure, this embodiment discloses a precise positioning device for a lattice column, which includes a lattice column body 1. A casing 2 is arranged on one side of the lattice column body 1. The casing 2 is sleeved on the surface of the lattice column body 1. A limiting device 3 is arranged on one side of the lattice column body 1. The limiting device 3 includes a rectangular frame 31. A connecting device 4 is arranged between the rectangular frame 31 and the casing 2. The rectangular frame 31 is sleeved on the surface of the lattice column body 1. Four sleeves 32 are symmetrically and fixedly connected to the surface of the rectangular frame 31. The inner walls of the four sleeves 32 are all rotatably connected with first screws 33. Threaded plates 35 are threadedly connected to the surfaces of the four first screws 33. On the side of the four threaded plates 35 close to the rectangular frame 31, scale rods 36 are fixedly connected. The surfaces of the four scale rods 36 are all slidably connected to the inner wall of the rectangular frame 31. The four scale rods 36 are all arranged inside the rectangular frame 31. The adjacent ends of the four scale rods 36 are all fixedly connected with positioning plates 37. The four positioning plates 37 are all arranged inside the rectangular frame 31. By setting the limiting device 3, first bury the casing 2 into the ground and find the central position inside the casing 2 through a measuring tool. At the same time, quickly assemble the limiting device 3 with the casing 2 through the connecting device 4, so that the central position of the rectangular frame 31 corresponds to the central position of the casing 2. At this time, use an external hoisting device to hoist and move the lattice column body 1. When the lattice column body 1 moves to the position where its surface enters the inside of the rectangular frame 31, stop moving the lattice column body 1, so that a part of the lattice column body 1 is located in the middle of the four positioning plates 37. At this time, manually rotate the four first screws 33, so that the four first screws 33 rotate along the inside of the four sleeves 32 respectively. Under the action of the threaded connection between the first screw 33 and the threaded plate 35, the four first screws 33 drive the four threaded rods to move left and right along their surfaces by rotation, so that the four threaded plates 35 drive the four scale rods 36 to move closer to each other along the inside of the rectangular frame 31 respectively, so that the four scale rods 36 drive the four positioning plates 37 to move closer to each other along the inside of the rectangular frame 31 respectively. At this time, the operator can observe the corresponding positions of the scales on the four scale rods 36 and the rectangular frame 31 to achieve precise adjustment of the moving positions of the four scale rods 36, so that the four positioning plates 37 can move precisely under the action of the four scale rods 36 and the four positioning plates 37 can be adjusted to an equal distance position, so that the central position of the four positioning plates 37 corresponds to the central position inside the casing 2. When the four positioning plates 37 move to the position where they are simultaneously in contact with the surface of the lattice column body 1 inside the rectangular frame 31, the four positioning plates 37 intercept the lattice column body 1 inside the rectangular frame 31, thereby achieving rapid positioning of the lattice column body 1. At this time, continue to lower the lattice column body 1 through the transmission of the hoisting device, so that the lattice column body 1 moves into the casing 2 and is intercepted and limited by the four positioning plates 37 during the movement, completing the rapid positioning effect during the installation of the lattice column body 1, reducing the inclination and shaking of the lattice column body 1 when it is placed inside the casing 2.The center position of the lattice column body 1 deviates from the center point position of the casing 2, resulting in a reduction in the installation quality of the lattice column body 1 and affecting the construction safety of the foundation pit steel strut and the capping beam.

A bolt 313 is threadedly connected to the inner wall of each of the four positioning rods 312. The size and shape of the surface of the bolt 313 are adapted to the size and shape of the inner wall of the circular hole 310. By providing the positioning rod 312 and the slide rail 39, first, manually move the positioning rod 312 so that the positioning rod 312 moves up and down along the inside of the slide rail 39. When the positioning rod 312 moves to an appropriate position inside the casing 2, make the inner wall of the circular hole 310 coincide with the inner wall of any hole on the positioning rod 312. At this time, rotate the bolt 313 with a tool so that the bolt 313 is inserted into any hole of the circular hole 310 and the positioning rod 312 to fix the position of the positioning rod 312, so that the positioning rod 312 enters the casing 2 and cooperates with the slide rail 39 to assist in intercepting the lattice column body 1 during the moving process, increasing the interception length of the lattice column body 1, and reducing the situation that the lattice column body 1 shakes briefly when it moves out of the limiting range of the positioning plate 37, resulting in a position deviation when the lattice column body 1 enters the casing 2 from the rectangular frame 31 and affecting the positioning effect, further improving the limiting effect on the lattice column body 1.
[0031] Referring to Figures 3-6 As shown, in this embodiment, a rectangular hole 311 is formed in one side of each of the four slide rails 39. A cylindrical block 314 is fixedly connected to one side of each of the four positioning rods 312. The four cylindrical blocks 314 are respectively located inside the four rectangular holes 311. By providing the cylindrical block 314, the cylindrical block 314 can be located inside the rectangular hole 311 to intercept and limit the positioning rod 312, reducing the situation that the positioning rod 312 shakes during the process of moving up and down along the inside of the slide rail 39 and affecting the limiting stability of the positioning rod 312 on the lattice column body 1, improving the use stability of the positioning rod 312. One end of each of the four first screws 33 away from the rectangular frame 31 is fixedly connected with an operation block 34. The cross section of the operation block 34 is cross-shaped. By providing the operation block 34, the operation block 34 can increase the contact area of the first screw 33, so that the operator can drive the first screw 33 to rotate quickly by manually rotating the operation block 34, improving the stability and convenience of manually rotating the first screw 33.

The surfaces of the plurality of rollers 38 are slightly higher than the surface of the positioning plate 37, and the plurality of rollers 38 are arranged at equal distances. By providing the rollers 38, the positioning plate 37 can be moved to the position where the surface of the roller 38 presses against the surface of the lattice column body 1 to achieve rapid positioning of the lattice column body 1. At the same time, under the rotation of the rollers 38, the wear on the surface of the positioning plate 37 generated during the movement of the lattice column body 1 into the inner part of the casing 2 can be reduced, and the situation where the surface of the positioning rod 312 is severely worn due to long-term contact with the surface of the lattice column body 1, which seriously affects the positioning accuracy, is reduced. The service life and efficiency of the positioning plate 37 are improved.
[0033] Refer to Figures 7-10 As shown in the figure, in this embodiment, the connecting device 4 includes a connecting block 41. The connecting block 41 is fixedly connected to the rectangular frame 31. A double-shaft motor 42 is fixedly connected to one side of the connecting block 41. Second screw rods 43 are fixedly connected to both output ends of the double-shaft motor 42. Threaded barrels 44 are threadedly connected to the surfaces of the two second screw rods 43. Clamping plates 45 are fixedly connected to one side of each of the two threaded barrels 44. The surface of the clamping plate 45 is arc-shaped. By providing the connecting device 4, first, manually move the rectangular frame 31, so that the rectangular frame 31 drives the connecting block 41 to move, so that the connecting block 41 drives the double-shaft motor 42 to move, so that the double-shaft motor 42 drives the two second screw rods 43 to move, so that the two second screw rods 43 drive the two threaded barrels 44 to move, so that the two threaded barrels 44 drive the two clamping plates 45 to move. When the rectangular frame 31 moves to the position where it fits against the surface of the opening of the casing 2, the casing 2 is located between the two clamping plates 45. At this time, start the double-shaft motor 42, so that the double-shaft motor 42 drives the two second screw rods 43 to rotate, so that the two second screw rods 43 drive the two threaded barrels 44 to move towards each other, so that the two threaded barrels 44 drive the two clamping plates 45 to move towards each other. When the two clamping plates 45 move to the position where they simultaneously press against the surface of the casing 2, the rectangular frame 31 is connected and fixed to the casing 2 under the clamping action of the two clamping plates 45 on the surface of the casing 2, thereby completing the rapid assembly of the limiting device 3 and the casing 2, enabling personnel to quickly disassemble the limiting device 3 after use, facilitating the repeated use of the limiting device 3, reducing material waste, and at the same time increasing the flexibility of use of the limiting device 3, enabling the limiting device 3 to be adapted to casings 2 of different sizes for use, and improving the use efficiency and practicality of the limiting device 3.
[0034] Refer to Figures 7-10As shown in the figure, in this embodiment, a plurality of top blocks 46 are fixedly connected to one side of each of the two clamping plates 45 close to the casing 2. The plurality of top blocks 46 are arranged at equal distances. The surface of the top block 46 is rectangular. By providing the top blocks 46, the plurality of top blocks 46 can improve the clamping efficiency of the clamping plate 45 and reduce the situation of sliding when the clamping plate 45 presses against the surface of the casing 2. At the same time, under the action of the plurality of top blocks 46, the force application points of the clamping plate 45 can be increased, so that the clamping plate 45 can still achieve the clamping effect when clamping the relatively small-sized casing 2. A plurality of reinforcing ribs 49 are fixedly connected to one side of each of the two clamping plates 45. The plurality of reinforcing ribs 49 are arranged at equal distances. By providing the reinforcing ribs 49, the reinforcing ribs 49 can increase the self-strength of the clamping plate 45, improve the toughness of the clamping plate 45, and reduce the situation of fracture or deformation of the clamping plate 45 when clamping the surface of the casing 2, resulting in the failure of the clamping plate 45 to clamp, thus improving the strength and clamping stability of the clamping plate 45.
[0035] Referring to Figures 7-10 As shown in the figure, in this embodiment, baffles 47 are fixedly connected to one end of each of the two second screws 43 away from the biaxial motor 42. The surface of the baffle 47 is larger than the inner wall of the threaded cylinder 44. By providing the baffle 47, the baffle 47 can intercept the threaded cylinder 44 during the moving process and reduce the situation of the threaded cylinder 44 accidentally disengaging from the surface of the second screw 43 when moving left and right along the surface of the second screw 43, thus improving the moving stability and safety of the threaded cylinder 44. Two circular hole plates 48 are symmetrically and fixedly connected to one end of the rectangular frame 31 close to the biaxial motor 42. The two circular hole plates 48 are respectively sleeved on the surfaces of the two second screws 43. By providing the circular hole plates 48, the circular hole plates 48 can assist in limiting and supporting the second screw 43 and reduce the situation of the second screw 43 shaking up and down during use, which affects the use effect, thus improving the use stability of the second screw 43. At the same time, it can prevent the threaded cylinder 44 from colliding with the surface of the biaxial motor 42 when moving left and right along the surface of the second screw 43.
[0036] The working principle is as follows: First, bury the casing 2 into the ground and find the central position inside the casing 2 through a measuring tool. At this time, manually move the rectangular frame 31, so that the rectangular frame 31 drives the connecting block 41 to move, so that the connecting block 41 drives the dual-axis motor 42 to move, so that the dual-axis motor 42 drives the two second screws 43 to move, so that the two second screws 43 drive the two threaded cylinders 44 to move, so that the two threaded cylinders 44 drive the two clamping plates 45 to move. When the rectangular frame 31 moves to the position where it fits the surface of the opening of the casing 2, the casing 2 is located between the two clamping plates 45. At this time, start the dual-axis motor 42, so that the dual-axis motor 42 drives the two second screws 43 to rotate, so that the two second screws 43 drive the two threaded cylinders 44 to move towards each other, so that the two threaded cylinders 44 drive the two clamping plates 45 to move towards each other. When the two clamping plates 45 move to the position where they simultaneously squeeze the surface of the casing 2, the rectangular frame 31 reaches the effect of connection and fixation with the casing 2 under the clamping action of the two clamping plates 45 on the surface of the casing 2, thus completing the rapid assembly of the limiting device 3 and the casing 2, making the central position of the rectangular frame 31 correspond to the central position of the casing 2. At this time, manually move the positioning rod 312, so that the positioning rod 312 moves up and down inside the slide rail 39. When the positioning rod 312 moves to an appropriate position inside the casing 2, the inner wall of the circular hole 310 coincides with the inner wall of any hole on the positioning rod 312. At this time, use a tool to rotate the bolt 313, so that the bolt 313 is screwed into any hole inside the circular hole 310 and the positioning rod 312 to fix the position of the positioning rod 312, so that the positioning rod 312 enters the casing 2 and cooperates with the slide rail 39 to assist in intercepting the lattice column body 1 during the moving process, increasing the interception length of the lattice column body 1. At this time, use an external hoisting device to hoist and move the lattice column body 1. When the lattice column body 1 moves to the position where its surface enters the rectangular frame 31, stop moving the lattice column body 1, so that a part of the lattice column body 1 is located in the middle of the four positioning plates 37. At this time, manually rotate the four first screws 33, so that the four first screws 33 rotate inside the four sleeves 32 respectively. Under the threaded connection of the first screw 33 and the screw hole plate 35, the four first screws 33 drive the four screw hole rods to move left and right along their surfaces by rotation, so that the four screw hole plates 35 drive the four scale rods 36 to move closer to each other inside the rectangular frame 31 respectively, so that the four scale rods 36 drive the four positioning plates 37 to move closer to each other inside the rectangular frame 31 respectively. At this time, the operator can observe the corresponding positions of the scales on the four scale rods 36 and the rectangular frame 31 to achieve precise adjustment of the moving positions of the four scale rods 36, so that the four positioning plates 37 move precisely under the action of the four scale rods 36 and the four positioning plates 37 can be adjusted to equal distance positions, making the central positions of the four positioning plates 37 correspond to the central position inside the casing 2, so that the four positioning plates 37 drive the multiple rollers 38 to move respectively,When the four positioning plates 37 move to the position where the surfaces of the multiple rollers 38 are simultaneously in contact with the surface of the lattice column body 1 inside the rectangular frame 31, the four positioning plates 37 cooperate with the multiple rollers 38 to intercept and limit the lattice column body 1 inside the rectangular frame 31, thereby achieving rapid positioning of the lattice column body 1. At this time, the lattice column body 1 is continuously lowered through the transmission of the hoisting equipment, so that the lattice column body 1 moves into the casing 2 and is intercepted and limited by the four positioning plates 37 and the multiple rollers 38 during the movement, completing the rapid positioning effect during the installation of the lattice column body 1.
