Description

Technical Field

[0001] This utility model relates to the field of civil engineering technology, specifically a board placement device for civil engineering. Background Technology

[0002] In the field of civil engineering construction, the efficiency of storage and transportation of materials (such as formwork, steel, precast components, etc.) directly affects the project progress and cost control.

[0003] However, existing devices mostly adopt a fixed frame structure, and the horizontal width and the spacing between the support plates cannot be adjusted. Traditional devices can only be adapted to a single specification, and multiple sets of equipment are required to meet different needs.

[0004] Furthermore, the adjustment of the support plate spacing relies on manual operation, requiring adjustment layer by layer through bolt tightening or hydraulic jacks. Each adjustment takes too long and the spacing error is too large, which seriously affects the stacking stability.

[0005] Based on this, a board placement device for civil engineering is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0006] The purpose of this invention is to provide a board placement device for civil engineering to solve the problems in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A panel placement device for civil engineering includes a base, a base frame fixedly installed at the middle of the upper end of the base, a central groove opened at the middle of the upper end of the base frame, two side frames symmetrically arranged on the left and right sides of the upper end of the base frame, a central block fixed at the middle of the lower end of the side frames, the central block being slidably installed inside the central groove, and a first adjustment structure for adjusting the relative distance between the two side frames being provided inside the central groove.

[0009] The side frame has an inner groove, and each of the two side frames has a through opening at the middle of its opposite ends. The through opening is connected to the inside of the inner groove. Several support plates are provided at the opposite ends of the two side frames. The inner groove has a second adjustment structure for adjusting the distance between two adjacent support plates.

[0010] Preferably, the first adjustment structure includes a motor installed at one end of the base frame, the output end of the motor extending into the center groove and fixedly connected to a bidirectional screw, the two ends of the bidirectional screw being threadedly connected to the center blocks at the lower middle of the two side frames respectively.

[0011] Preferably, two side blocks are symmetrically fixed on the front and rear sides of the lower end of the side frame, and two side grooves are symmetrically opened on the front and rear sides of the upper end of the base frame, with each side block slidably installed inside one side groove.

[0012] Preferably, the second adjustment structure includes a plurality of spacer blocks disposed inside the inner groove. One end of each spacer block is fixed with a connecting block, which passes through a through-hole and is fixedly connected to a support plate. The plurality of spacer blocks are distributed vertically inside the inner groove. Two sliders are disposed between every two spacer blocks. The two sliders are symmetrically arranged front and back. Both ends of the sliders are hinged to two connecting plates, and the other end of the connecting plates is hinged to the spacer block.

[0013] Preferably, the second adjustment structure further includes two symmetrically arranged movable blocks at the bottom of the inner groove. The upper end of the movable block is hinged to one end of the connecting plate, and the other end of the connecting plate is hinged to the lower end of the lowest spacer block. The two movable blocks are respectively threaded to both ends of the bidirectional screw rod. The bidirectional screw rod is rotatably installed inside the inner groove, and one end of the bidirectional screw rod is fixedly connected to the output end of the motor.

[0014] Preferably, the two symmetrical sliders are slidably mounted on the guide rod, and guide blocks are fixed at both ends of the guide rod. Guide grooves are provided at both the front and rear ends of the inner wall of the inner groove, and the inner wall of the guide groove is slidably connected to the outer wall of the guide block.

[0015] Preferably, each of the lower corners of the base is equipped with lockable casters.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model uses a motor to drive a bidirectional screw to adjust the relative distance between the two side frames, so that the lateral width of the device can be steplessly adjusted between the minimum compact state and the maximum extended state, adapting to the support requirements of plates of different lengths.

[0018] 2. This utility model uses a second motor to drive a second bidirectional screw, which in turn drives two moving blocks to move in opposite directions within the inner groove of the base frame. The moving blocks are hinged to the lowest layer spacer block via a connecting plate. When the moving blocks approach each other, the connecting plate drives the spacer block to rise; when the moving blocks move away from each other, the connecting plate drives the spacer block to sink downwards. Furthermore, the stable sliding of the slider on the guide rod enables synchronous adjustment of the equal spacing between the multiple layers of support plates, ensuring a uniform vertical spacing between each layer.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] In one embodiment, such as Figures 1-4 As shown, a panel placement device for civil engineering includes a base 1, a base frame 2 fixedly installed at the middle of the upper end of the base 1, a central groove 21 opened at the middle of the upper end of the base frame 2, two side frames 4 symmetrically arranged on the left and right sides of the upper end of the base frame 2, a central block 43 fixed at the middle of the lower end of the side frame 4, the central block 43 being slidably installed inside the central groove 21, and a first adjustment structure 3 for adjusting the relative distance between the two side frames 4 being provided inside the central groove 21;

[0026] The side frame 4 has an inner groove 41 inside, and each of the two side frames 4 has a through opening 42 at the middle of its opposite ends. The through opening 42 is connected to the inside of the inner groove 41. Several support plates 6 are provided at the opposite ends of the two side frames 4. The inner groove 41 is provided with a second adjustment structure 5 for adjusting the distance between two adjacent support plates 6.

[0027] In this embodiment, when it is necessary to adapt to plates of different lengths, the relative distance between the two side frames 4 is adjusted by the first adjustment structure 3; for the stacking requirements of plates of different thicknesses, the second adjustment structure 5 adjusts the distance between two adjacent support plates 6, so as to realize the synchronous adjustment of the equal spacing of the multi-layer support plates 6 and ensure that the plates of each layer maintain a uniform vertical spacing.

[0028] In an optional embodiment, the first adjustment structure 3 includes a motor 31 mounted on one end of the base frame 2. The output end of the motor 31 extends into the center groove 21 and is fixedly connected to a bidirectional screw 32. The two ends of the bidirectional screw 32 are respectively threadedly connected to the center blocks 43 at the lower middle of the two side frames 4.

[0029] It should be noted that when motor 31 rotates clockwise, the left-hand section of the bidirectional screw 32 drives the left center block 43 to move to the right, and the right-hand section simultaneously drives the right center block 43 to move to the left. The two side frames 4 move towards each other with the center groove 21 as the guide rail, realizing the lateral contraction of the device. When motor 31 rotates counterclockwise, the bidirectional screw 32 rotates in the opposite direction, the two center blocks 43 move outward in sync, and the side frames 4 unfold in the opposite direction, expanding the lateral bearing capacity of the device. Thus, it can adapt to plates of different lengths.

[0030] In an optional embodiment, two side blocks 44 are symmetrically fixed on the front and rear sides of the lower end of the side frame 4, and two side grooves 22 are symmetrically opened on the front and rear sides of the upper end of the base frame 2, with each side block 44 slidably installed inside a side groove 22.

[0031] It should be noted that the side groove 22 and the side block 44 are dovetail groove mating structures, which restrict the movement trajectory of the side frame 4 and prevent skewing or shaking during the adjustment process.

[0032] In an optional embodiment, the second adjustment structure 5 includes a plurality of spacer blocks 55 disposed inside the inner groove 41. One end of each spacer block 55 is fixed with a connecting block 59. The connecting block 59 passes through the through opening 42 and is fixedly connected to the support plate 6. The plurality of spacer blocks 55 are distributed vertically inside the inner groove 41. Two sliders 56 are disposed between every two spacer blocks 55. The two sliders 56 are symmetrically arranged front and back. The two ends of each slider 56 are respectively hinged to two connecting plates 54. The other end of each connecting plate 54 is hinged to the spacer block 55.

[0033] It should be noted that a number of spacer blocks 55 and a number of sliders 56 form a scissor mechanism, thereby ensuring that the distance between every two spacer blocks 55 is the same, thus meeting the stacking requirements of plates of different thicknesses.

[0034] In an optional embodiment, the second adjustment structure 5 further includes two movable blocks 53 symmetrically arranged at the bottom of the inner groove 41. The upper end of the movable block 53 is hinged to one end of the connecting plate 54, and the other end of the connecting plate 54 is hinged to the lower end of the lowest spacer block 55. The two movable blocks 53 are respectively threaded to both ends of the bidirectional screw 52. The bidirectional screw 52 is rotatably installed inside the inner groove 41, and one end of the bidirectional screw 52 is fixedly connected to the output end of the motor 51.

[0035] It should be noted that the motor 51 drives the bidirectional screw 52 to rotate, which in turn drives the two moving blocks 53 to move in the inner groove 41 of the base frame. When the moving blocks 53 move closer to each other, the connecting plate 54 drives the spacer block 55 to rise upward; when the moving blocks 53 move away from each other, the connecting plate 54 drives the spacer block 55 to sink downward. This achieves the synchronous adjustment of the equal spacing of the multi-layer support plates 6, ensuring that the vertical spacing between each layer of plates remains uniform.

[0036] In an optional embodiment, two symmetrical sliders 56 are slidably mounted on a guide rod 57, both ends of which are fixed with guide blocks 58. Guide grooves 411 are provided at both the front and rear ends of the inner wall of the inner groove 41, and the inner wall of the guide groove 411 is slidably connected to the outer wall of the guide block 58.

[0037] It should be noted that by having the guide blocks 58 at both ends of the guide rod 57 slide in the guide groove 411, the scissor lifting mechanism formed in the second adjustment structure 5 can operate stably, realize the relative distance of several spacer blocks 55, and further realize the equal spacing synchronous adjustment of the multi-layer support plates 6, ensuring that the vertical spacing between each layer of plates is maintained.

[0038] In an optional embodiment, lockable casters are installed at the lower corners of the base 1.

[0039] It should be noted that the lockable casters allow for both flexible movement of the device between construction sites and static storage.

[0040] The above embodiment discloses a sheet metal placement device for civil engineering. When the lateral width of the device needs adjustment, a motor 31 at one end of the base frame 2 is activated, driving a bidirectional screw 32 to rotate within the central groove 21. Since the central blocks 43 at the lower ends of the two side frames 4 respectively engage with the forward and reverse threaded sections of the bidirectional screw 32, under the guidance of the side blocks 44 and the side groove 22, the two side frames 4 will move synchronously in opposite directions along the central groove 21. This design allows the lateral width of the device to be steplessly adjusted between its minimum compact state and its maximum extended state, adapting to the support requirements of sheet metal of different lengths.

[0041] To address the stacking requirements of sheets of varying thicknesses, the second adjustment structure 5 uses a motor 51 to drive a bidirectional screw 52 to rotate, causing two moving blocks 53 to move in opposite directions within the inner groove 41 of the base frame. The moving blocks 53 are hinged to the bottommost spacer block 55 via a connecting plate 54. When the moving blocks 53 approach each other, the connecting plate 54 drives the spacer block 55 to rise; when the moving blocks 53 move away from each other, the connecting plate 54 causes the spacer block 55 to sink downwards. This scissor-type lifting mechanism, through the stable sliding of the slider 56 on the guide rod 57, achieves synchronous adjustment of the multiple layers of support plates 6 at equal intervals, ensuring a uniform vertical spacing between each layer of sheet metal.

[0042] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
