Abstract
Description
Technical Field
[0001] This utility model belongs to the field of fire protection facility installation technology, specifically relating to a fire hydrant box installation support device. Background Technology
[0002] Fire hydrant boxes are devices used to store fire hydrants and related fire extinguishing equipment. During installation, the fire hydrant box needs to be lifted to a designated position and then fixed to the building wall surface using expansion bolts. In actual installation, the lifting and support of the fire hydrant box often relies on manual labor. This method poses certain safety hazards and has low adjustment efficiency and accuracy.
[0003] Chinese patent CN119770900A discloses a fire box mounting and fixing support base. This design includes a support assembly and a load-bearing assembly. The support assembly includes a support member, a threaded adjusting member, and a sliding block. Two threaded adjusting members are symmetrically arranged. Each threaded adjusting member includes a threaded post, an internal threaded cylinder, and an outer ring. The threaded post is fixedly connected to the support member, the internal threaded cylinder is threadedly fitted onto the threaded post, and the sliding block is slidably fitted onto the threaded post, abutting against the top of the internal threaded cylinder. The load-bearing assembly includes a load-bearing plate, an adjusting limit, and a bubble level. The end of the load-bearing plate is rotatably connected between the two sliding blocks. This design utilizes the rotation of the outer ring to drive the internal threaded cylinder, adjusting both the height and the inclination of the load-bearing plate, thus supporting the fire box body in the installation position and ensuring its horizontal and vertical alignment.
[0004] In the above scheme, the bearing plate has a fixed length, the two threaded columns are arranged in parallel, and the sliding block is slidably sleeved on the threaded column. When only one internal threaded sleeve is rotated, the bearing plate is difficult to tilt, which makes it difficult to adjust the bearing plate to a horizontal state. Utility Model Content
[0005] The present invention aims to provide a fire hydrant box installation support device to solve the problem of difficulty in adjusting the bearing plate to a horizontal state in the above-mentioned solutions.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A fire hydrant box installation support device includes a base and a support plate. Scissor lifters are respectively provided at both ends of the top of the base. A first movable frame and a second movable frame are respectively connected to the top of the two scissor lifters. A fixed shaft is provided at the top of the first movable frame. A movable seat is slidably inserted into the top of the second movable frame. A lifting component for raising the movable seat is provided inside the second movable frame. A driving component for folding the two scissor lifters is provided at the top of the base. A sliding groove is provided on the side wall of one end of the support plate. The other end of the support plate is rotatably connected to the movable seat. The fixed shaft is slidably inserted into the sliding groove. A clamping component for clamping the fire hydrant box is provided at the top of the support plate.
[0008] The principle and effects of this technical solution:
[0009] In the initial state, the scissor lift is folded and the support plate is in a low position. When installing the fire hydrant box, first place the device below the installation point, then place the fire hydrant box on top of the support plate, so that the clamping assembly clamps and fixes the fire hydrant box. Then, use the drive assembly to extend the scissor lift, thereby raising the support plate to an appropriate height. Then, use the lifting assembly to move the movable seat upward, and the support plate rotates along the rotation connection point with the movable seat. During this process, one end of the support plate rotates relative to the fixed axis and also moves relative to the fixed axis until the support plate is adjusted to a horizontal state. At this time, the fire hydrant box placed on top of the support plate is in a horizontal state.
[0010] The above setup allows staff to easily lift the fire hydrant box to the appropriate height without requiring continuous manual support, saving manpower and reducing safety hazards. It also makes it easier for staff to adjust the support plate to be level, improving the installation accuracy and effectiveness of the fire hydrant box.
[0011] In this utility model, the top of the second movable frame is provided with a slot, the inner side wall of the slot is provided with a limiting groove, the lifting component includes a wedge block that is slidably inserted into the limiting groove, the side of the wedge block away from the slot is rotatably connected to a first threaded rod, the first threaded rod is threaded through the second movable frame, and the bottom of the movable seat is provided with a guide slope that cooperates with the wedge block.
[0012] The principle and effects of this technical solution:
[0013] In the initial state, one end of the wedge block extends into the slot to provide support for the movable seat. When the movable seat needs to be moved upward, the first threaded rod is rotated to push the wedge block to continue moving into the slot. During the process of the wedge block moving into the slot, it pushes the movable seat upward. The guide ramp of the movable seat continuously presses against the wedge block under the gravity of the bearing plate and the fire hydrant box.
[0014] The above settings achieve the goal of moving the movable seat upwards, while also preventing it from moving downwards when it is moved to an appropriate height, further facilitating the adjustment and installation of the fire hydrant box by staff.
[0015] In this utility model, the driving assembly includes a first guide rod fixedly disposed on the top of the base, a bidirectional screw rotatably disposed on the top of the base, and a motor that is drivenly connected to the bidirectional screw. The positive and negative threaded sections of the bidirectional screw are respectively symmetrically fitted with sliders. The sliders are slidably fitted on the first guide rod. The bottom ends of the two scissor lifts are rotatably connected to the top of the base at opposite ends, and the bottom ends of the two scissor lifts are rotatably connected to the corresponding sliders at opposite ends.
[0016] The principle and effects of this technical solution:
[0017] When the support plate needs to be lifted, the motor drives the bidirectional screw to rotate. Because the first guide rod prevents the slider from rotating along the axial direction of the bidirectional screw, the two sliders move away from each other as the bidirectional screw rotates, and the two ends of the bottom of the scissor lift move closer to each other, thereby causing the top of the scissor lift to move upward.
[0018] The above settings achieve the purpose of extending the scissor lift using the drive assembly, thereby raising the support plate and improving the ease of operation of this device.
[0019] In this utility model, a through groove is provided on one side of the top of the bearing plate, and the clamping assembly includes a second threaded rod rotatably inserted into the through groove, a second guide rod fixedly disposed on both sides of the second threaded rod in the through groove, a movable block that is fitted onto the second threaded rod and slidably fitted onto the second guide rod, and a fixed block fixedly disposed on the other side of the top of the bearing plate.
[0020] The principle and effects of this technical solution:
[0021] After placing the fire hydrant box on top of the support plate between the movable block and the fixed block, rotate the second threaded rod. Because the second guide rod prevents the movable block from rotating with the second screw, the movable block moves towards the fixed block as the second threaded rod rotates, until the movable block and the fixed block are pressed against the two sides of the fire hydrant box respectively.
[0022] The above-mentioned design prevents the fire hydrant box from moving laterally when the support plate is lifted, thus improving the stability of the device during use.
[0023] In this invention, anti-slip pads are fixedly provided on the sides of both the fixed block and the movable block that are close to each other. This arrangement increases the friction between the movable block and the fixed block and the fire hydrant box, further improving the clamping effect on the fire hydrant box.
[0024] In this invention, a level is provided on the side wall of the support plate. This feature allows workers to easily determine whether the support plate is level.
[0025] In this invention, telescopic rods are fixedly connected to both ends of the bottom of the first movable frame and both ends of the bottom of the second movable frame, and the bottom of each telescopic rod is fixedly connected to the top of the base. This arrangement ensures that the first and second movable frames move vertically as the scissor lift extends and retracts, preventing rotation of the first and second movable frames and improving the stability of the device during use.

[0033] Example:
[0034] As attached Figure 1-5As shown, this utility model discloses a fire hydrant box installation support device, including a base 10 and a support plate 70. Scissor lifters 20 are respectively provided at both ends of the top of the base 10. A first movable frame 30 and a second movable frame 40 are respectively connected to the top of the two scissor lifters 20. A fixed shaft 31 is provided at the top of the first movable frame 30. A movable seat 41 is slidably inserted into the top of the second movable frame 40. A lifting assembly for lifting the movable seat 41 is provided inside the second movable frame 40. A driving assembly for folding the two scissor lifters 20 is provided at the top of the base 10. A sliding groove 71 is provided on the side wall of one end of the support plate 70. The other end of the support plate 70 is rotatably connected to the movable seat 41. The fixed shaft 31 is slidably inserted into the sliding groove 71. A clamping assembly for clamping the fire hydrant box is provided at the top of the support plate 70.
[0035] In this embodiment, the top of the second movable frame 40 is provided with a slot 42, and the inner side wall of the slot 42 is provided with a limiting groove 43. The lifting component includes a wedge block 51 that is slidably inserted into the limiting groove 43. The side of the wedge block 51 away from the slot 42 is rotatably connected to a first threaded rod 52. The first threaded rod 52 is threaded through the second movable frame 40. The bottom of the movable seat 41 is provided with a guide slope that cooperates with the wedge block 51.
[0036] In this embodiment, the driving assembly includes a first guide rod 61 fixedly disposed on the top of the base 10, a bidirectional screw 62 rotatably disposed on the top of the base 10, and a motor 63 that is drively connected to the bidirectional screw 62. The forward and reverse threaded sections of the bidirectional screw 62 are respectively symmetrically fitted with sliders 64. The sliders 64 are slidably fitted on the first guide rod 61. The bottom ends of the two scissor lifts 20 are rotatably connected to the top of the base 10 at opposite ends, and the bottom ends of the two scissor lifts 20 are rotatably connected to the corresponding sliders 64 at opposite ends. The motor 63 is fixedly disposed on the top of the base 10.
[0037] In this embodiment, a through groove 72 is provided on one side of the top of the bearing plate 70. The clamping assembly includes a second threaded rod 81 rotatably inserted into the through groove 72, a second guide rod 82 fixedly disposed on both sides of the second threaded rod 81 in the through groove 72, a movable block 83 that is fitted onto the second threaded rod 81 and slidably fitted onto the second guide rod 82, and a fixing block 84 fixedly disposed on the other side of the top of the bearing plate 70.
[0038] In this embodiment, anti-slip pads 85 are fixedly provided on the side of the fixed block 84 and the movable block 83 that are close to each other.
[0039] In this embodiment, a level 73 is provided on the side wall of the support plate 70.
[0040] In this embodiment, telescopic rods 90 are fixedly connected to both ends of the bottom of the first movable frame 30 and both ends of the bottom of the second movable frame 40, and the bottom of each telescopic rod 90 is fixedly connected to the top of the base 10.
[0041] The specific implementation process is as follows:
[0042] In the initial state, the scissor lift 20 is folded, and the support plate 70 is in a low position. When installing the fire hydrant box, first place the device below the installation point, then place the fire hydrant box on top of the support plate 70, so that the clamping assembly clamps and fixes the fire hydrant box. Then, use the drive assembly to extend the scissor lift 20, thereby raising the support plate 70 to an appropriate height. Then, use the lifting assembly to move the movable seat 41 upward, and the support plate 70 rotates along the rotation connection point with the movable seat 41. During this process, one end of the support plate 70 rotates relative to the fixed shaft 31 and also moves relative to the fixed shaft 31 until the support plate 70 is adjusted to a horizontal state. At this time, the fire hydrant box placed on top of the support plate 70 is in a horizontal state.
[0043] In the initial state, one end of the wedge block 51 extends into the slot 42 to provide support for the movable seat 41. When the movable seat 41 needs to be moved upward, the first threaded rod 52 is rotated to push the wedge block 51 to continue moving into the slot 42. During the process of the wedge block 51 moving into the slot 42, it pushes the movable seat 41 to move upward. The guide slope of the movable seat 41 continuously presses against the wedge block 51 under the gravity of the bearing plate 70 and the fire hydrant box.
[0044] When it is necessary to lift the support plate 70, the motor 63 drives the bidirectional screw 62 to rotate. Because the first guide rod 61 prevents the slider 64 from rotating along the axial direction of the bidirectional screw 62, the two sliders 64 move away from each other as the bidirectional screw 62 rotates, and the two ends of the bottom of the scissor lift 20 move closer to each other, thereby causing the top of the scissor lift 20 to move upward.
[0045] After placing the fire hydrant box on top of the bearing plate 70 between the movable block 83 and the fixed block 84, rotate the second threaded rod 81. Because the second guide rod 82 prevents the movable block 83 from rotating with the second screw, the movable block 83 moves towards the fixed block 84 as the second threaded rod 81 rotates, until the movable block 83 and the fixed block 84 are respectively pressed against the two sides of the fire hydrant box.
[0046] The parts of the device not covered herein are the same as or can be implemented using existing technologies.
