Description

Technical Field

[0001] This invention belongs to the field of building engineering, and in particular relates to a liftable support for building construction. Background Technology

[0002] During construction, in order to facilitate the work of construction workers, it is often necessary to lift building materials such as bricks and gravel to a high place. Most existing lifting methods involve placing the bricks, gravel, etc. to be laid on a platform, and then using a simple lifting structure to lift the platform up, such as a hand-operated hoist. This type of lifting structure is characterized by its simple structure and convenient operation.

[0003] A lifting support for construction engineering disclosed in Chinese Utility Model Patent Application Publication CN212474928U includes a support body and a construction platform installed on the upper end of the support body. The construction platform is provided with lifting holes. Although this utility model fixes one end of the material feeding trough to the belt and drives the belt to rotate cyclically by the motor, ensuring the cyclic feeding of the lifting support and improving work efficiency, the belt is made of flexible material and the material feeding trough is only fixed to the belt at one end, with the other end suspended in the air. As a result, when the material placed in the material feeding trough is heavy, the material feeding trough will tilt to one side, and the material inside will spill out, posing a danger and making it inconvenient to use. Moreover, since the electric motor is directly used as the power source, when the electric motor is powered off, the material feeding trough can easily drive the electric motor to reverse, which can also be dangerous.

[0004] To avoid the aforementioned technical problems, it is indeed necessary to provide a liftable support for building construction to overcome the deficiencies in the prior art. Summary of the Invention

[0005] The purpose of this invention is to provide a liftable support for construction engineering, which aims to solve the problems caused by tilting of the material discharge chute and reverse rotation of the motor.

[0006] This invention is implemented as follows: a liftable support for construction engineering includes a base plate and a construction frame. The construction frame is fixedly connected to the base plate, and two mounting plates are fixedly connected to the construction frame. The two mounting plates are fixedly connected by connecting columns, and each of the two mounting plates has an annular groove on its opposite side. A plurality of material boxes are slidably connected between the two annular grooves, and sliding columns adapted to the annular grooves are fixedly connected to the sides of the material boxes. The invention also includes:

[0007] The drive mechanism is connected to two mounting plates and is fixedly connected to all the material boxes. The drive mechanism is used to drive the material boxes to move along the annular slide groove.

[0008] An auxiliary mechanism is connected to the mounting plate and is connected to the material box via a transmission connection. The auxiliary mechanism is used to maintain the stability of the material box during movement.

[0009] An auxiliary safety mechanism is fixedly connected to one of the mounting plates. A triangular locking block that cooperates with the auxiliary safety mechanism is fixedly connected to the side of the drive mechanism near the auxiliary safety mechanism. When the drive mechanism reverses, the triangular locking block prevents the drive mechanism from continuing to move by abutting against the auxiliary safety mechanism.

[0010] In a further technical solution, the driving mechanism includes two rotating rods rotatably connected between two mounting plates. A transmission roller is fixedly connected to each of the two rotating rods, and a conveyor belt is driven between the two transmission rollers. The conveyor belt is fixedly connected to all the material boxes. A motor is fixedly mounted on the side of one of the mounting plates, and the output shaft of the motor is fixedly connected to one end of one of the rotating rods.

[0011] In a further technical solution, the auxiliary mechanism includes an inner gear ring and an outer gear ring fixedly connected to the mounting plate. The inner gear ring and the outer gear ring are respectively disposed on both sides of the annular slide groove. Two auxiliary gears are rotatably connected to the material box, and the two auxiliary gears are respectively meshed with the outer gear ring and the inner gear ring.

[0012] In a further technical solution, the number of auxiliary mechanisms is two, and the two auxiliary mechanisms are respectively connected to the opposite sides of the two mounting plates, and the two auxiliary mechanisms are symmetrically distributed about the material box.

[0013] In a further technical solution, the auxiliary safety mechanism includes a fixed frame fixedly connected to one of the mounting plates. The fixed frame has a groove at one end near the transmission roller for the triangular block to pass through. Both sides of the groove have mounting slots. A locking plate is slidably connected inside the two mounting slots. A compression spring is provided between the locking plate and the mounting slot. The triangular block is fixedly connected to the side of the transmission roller near the fixed frame.

[0014] In a further technical solution, there are two mounting slots on the same side of the groove. The upper mounting slot is provided with a first electrode post inside, and a second electrode post is provided on the side of the corresponding card plate. Both the first electrode post and the second electrode post are electrically connected to the motor. When the first electrode post and the second electrode post are electrically connected, the motor stops running.

[0015] In a further technical solution, there are multiple triangular blocks, and all of the multiple triangular blocks are distributed in a ring array around the axis of the transmission roller.

[0016] A further technical solution is that the bottom of the base plate is equipped with casters.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] The present invention provides a liftable support for construction engineering. During the process of the material box being lifted by the motor through the conveyor belt, two gears mesh with the outer gear ring and the inner gear ring respectively, so that both ends of the material box are subjected to force. The outer gear ring provides an upward support force to the material box, preventing the material box from tilting to one side and maintaining the stability of the material box, making the device easy to use.

[0019] The present invention provides a liftable support for construction engineering. When the motor reverses, the triangular block on the transmission roller abuts against the plate, thereby preventing the transmission roller from continuing to rotate, which can prevent the material box from falling and avoid the danger caused by reversal. When the motor is running normally, the triangular block is engaged between the two plates above, thereby electrically connecting the first electrode post and the second electrode post, stopping the motor and facilitating the unloading of materials by the workers.

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0027] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0028] like Figure 1-5 As shown, this invention provides a liftable support frame for construction engineering, comprising a base plate 1 and a construction frame 2. The construction frame 2 is fixedly connected to the base plate 1. Two mounting plates 3 are fixedly connected to the construction frame 2, both of which penetrate the construction frame 2. The two mounting plates 3 are fixedly connected by connecting columns 4, and each of the two mounting plates 3 has an annular groove 5 on its opposite side. A plurality of material boxes 6 are slidably connected between the two annular grooves 5. The sides of the material boxes 6 are fixedly connected with sliding columns adapted to the annular grooves 5. The invention also includes:

[0029] The drive mechanism 7 is connected to two mounting plates 3 and is fixedly connected to all the material boxes 6. The drive mechanism 7 is used to drive the material boxes 6 to move along the annular slide groove 5.

[0030] Auxiliary mechanism 8 is connected to the mounting plate 3 and is connected to the material box 6 via a transmission connection. The auxiliary mechanism 8 is used to maintain the stability of the material box 6 during movement.

[0031] An auxiliary safety mechanism 9 is fixedly connected to one of the mounting plates 3. A triangular locking block 10 that cooperates with the auxiliary safety mechanism 9 is fixedly connected to the side of the drive mechanism 7 near the auxiliary safety mechanism 9. When the drive mechanism 7 reverses, the triangular locking block 10 prevents the drive mechanism 7 from continuing to move by abutting against the auxiliary safety mechanism 9.

[0032] In embodiments of the present invention, such as Figure 2-3 As shown, in a preferred embodiment of the present invention, the driving mechanism 7 includes two rotating rods 71 ​​rotatably connected between two mounting plates 3. A transmission roller 72 is fixedly connected to each of the two rotating rods 71. A conveyor belt 73 is driven between the two transmission rollers 72. The conveyor belt 73 is fixedly connected to all the material boxes 6. A motor 74 is fixedly mounted on the side of one of the mounting plates 3. The output shaft of the motor 74 is fixedly connected to one end of one of the rotating rods 71.

[0033] In embodiments of the present invention, such as Figure 2-3 As shown, in a preferred embodiment of the present invention, the auxiliary mechanism 8 includes an internal gear ring 81 and an external gear ring 82 fixedly connected to the mounting plate 3. The internal gear ring 81 and the external gear ring 82 are respectively disposed on both sides of the annular slide groove 5. Two auxiliary gears 83 are rotatably connected to the material box 6, and the two auxiliary gears 83 are respectively meshed with the external gear ring 82 and the internal gear ring 81.

[0034] The conveyor belt 73 drives the material box 6 to move, and the material box 6 drives the auxiliary gear 83 to move. Under the action of the outer gear ring 82 and the inner gear ring 81, the auxiliary gear 83 rotates. At the same time, the outer gear ring 82 and the inner gear ring 81 also provide an upward support force to the auxiliary gear 83, so that the material box 6 can maintain balance and not tilt to one side.

[0035] In embodiments of the present invention, such as Figure 1 As shown, in a preferred embodiment of the present invention, there are two auxiliary mechanisms 8. The two auxiliary mechanisms 8 are respectively connected to the opposite sides of the two mounting plates 3, and the two auxiliary mechanisms 8 are symmetrically distributed about the material box 6, so that the material box 6 has better stability.

[0036] In embodiments of the present invention, such as Figure 5 As shown, in a preferred embodiment of the present invention, the auxiliary safety mechanism 9 includes a fixed frame 91 fixedly connected to one of the mounting plates 3. The fixed frame 91 has a groove at one end near the transmission roller 72 for the triangular block 10 to pass through. The two side walls of the groove are provided with mounting slots 92. The two mounting slots 92 are slidably connected with a locking plate 93. A compression spring 94 is provided between the locking plate 93 and the mounting slot 92. The triangular block 10 is fixedly connected to the side of the transmission roller 72 near the fixed frame 91.

[0037] When the motor 74 is running normally, the triangular block 10 passes between the two clamping plates 93. The two clamping plates 93 move to both sides without blocking the movement of the triangular block 10. When the triangular block 10 passes through the clamping plates 93, the compression spring 94 drives the clamping plates 93 back to their original position. When the conveyor belt 73 pulls the drive roller 72 in reverse, the bottom of the triangular block 10 abuts against the two clamping plates 93, thereby preventing the drive roller 72 from rotating and preventing the conveyor belt 73 from continuing to move, thus avoiding an accident.

[0038] In embodiments of the present invention, such as Figure 5 As shown, in a preferred embodiment of the present invention, there are two mounting slots 92 located on the same side of the groove. The upper mounting slot 92 is provided with a first electrode post 95 inside, and a second electrode post 96 is provided on the side of the corresponding card plate 93. Both the first electrode post 95 and the second electrode post 96 are electrically connected to the motor 74. Preferably, a control device is added, and the first electrode post 95, the second electrode post 96 and the motor 74 are all electrically connected to the control device. When the first electrode post 95 and the second electrode post 96 are electrically connected, the control device controls the motor 74 to stop running.

[0039] When the triangular locking block 10 is engaged between the two upper locking plates 93, the triangular locking block 10 presses the locking plates 93, causing the locking plates 93 to move inward, thereby causing the first electrode post 95 to come into contact with the second electrode post 96. Then the motor 74 stops running, and the material box 6 stops moving, making it convenient for workers to unload materials. There is no need to manually control the motor 74 to stop running, avoiding the danger caused by operational errors during manual control.

[0040] In embodiments of the present invention, such as Figure 3 As shown, in a preferred embodiment of the present invention, there are multiple triangular locking blocks 10, all of which are arranged in a circular array around the axis of the transmission roller 72. This increases the number of triangular locking blocks 10, ensuring that they can promptly engage with the locking plate 93 in the event of a reversal, thus enhancing the safety of the device.

[0041] In this embodiment of the invention, as a preferred embodiment, the bottom of the base plate 1 is provided with casters to facilitate the movement of the device.

[0042] This construction project uses a liftable support frame. During use, building materials are placed in the material box 6, and the motor 74 is turned on. The motor 74 drives a rotating rod 71 to rotate, which in turn drives a transmission roller 72 to rotate. The transmission roller 72 drives a conveyor belt 73 to rotate, which in turn moves the material box 6 along the annular groove 5, achieving cyclical lifting of the material box 6. During the lifting process, the material box 6 drives the auxiliary gear 83 to move. Under the action of the outer gear ring 82 and the inner gear ring 81, the auxiliary gear 83 rotates. Simultaneously, the outer gear ring 82 and the inner gear ring 81 also provide an upward supporting force to the auxiliary gear 83, thus… This ensures that the material box 6 remains balanced and does not tilt to one side, preventing the building materials from spilling. When the triangular locking block 10 engages between the two upper locking plates 93, the triangular locking block 10 presses against the locking plates 93, causing the locking plates 93 to move inward. This causes the first electrode post 95 to come into contact with the second electrode post 96, stopping the motor 74 and stopping the material box 6 from moving, making it easier for workers to unload materials. When the conveyor belt 73 pulls the drive roller 72 in reverse, the bottom of the triangular locking block 10 comes into contact with the two locking plates 93, preventing the drive roller 72 from rotating and stopping the conveyor belt 73 from continuing to move, thus preventing accidents.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0044] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
