Description

Technical Field

[0001] This invention relates to the field of construction equipment technology, specifically to a high-efficiency brick-passing device for construction. Background Technology

[0002] During construction, when the wall reaches a certain height, the bricks on the ground need to be transported to the top to continue construction. The traditional method of manually passing them one by one is not only inefficient, but may also lead to improper handover and bricks falling, posing certain safety hazards.

[0003] A brick lifting device for construction, authorized in China (publication number CN112407773A), utilizes a lifting lever on a conveyor belt to continuously lift bricks placed on a loading platform. A swinging mechanism then drives a discharging lever to oscillate back and forth, discharging the bricks loaded on the lifting lever into a discharging hopper. This achieves automatic and continuous loading and unloading of bricks, resulting in high lifting efficiency, significant labor savings, and safety and stability. The height of the lifting platform can be adjusted according to different construction heights. Simultaneously, first and second tensioning components ensure the conveyor belt remains taut, preventing slippage and guaranteeing the stability of the brick lifting operation. However, this invention has the following problems in use:

[0004] (1) The inclined conveyor belt of this invention may occupy a large area. The above situation may hinder construction to a certain extent. In particular, when the user is doing bricklaying work, he / she needs to stand on the construction scaffold while laying bricks and taking out the transported bricks in time. Since the scaffold used for bricklaying is generally not large, it is not possible to stack too many bricks. After the lifting lever moves the bricks in the receiving slot away, bricks can be placed into the receiving slot. During the construction process, it may be necessary to frequently start the conveyor belt or stop placing bricks on the conveyor belt. The former affects the brick transportation efficiency and reduces the practicality. It cannot adjust the brick transportation situation in time according to the user's situation. The latter causes the waste of electricity when the conveyor belt is idle.

[0005] (2) The device and some existing technologies require workers to continuously place bricks into the receiving trough during transportation and cannot leave the device until no more bricks need to be added above. When the bricks are transported to the top one by one, the bricks cannot be automatically stacked in the feeding hopper. The feeding hopper can only hold a limited number of bricks, which are mainly received by workers on the construction frame above. If the workers fail to take the bricks out of the feeding hopper in time, it may cause the subsequent bricks to be unable to continue to be transported smoothly, and the conveyor belt to be jammed, etc.

[0006] Therefore, the present invention provides a high-efficiency brick-passing device for building construction. Summary of the Invention

[0007] To address the problems in existing technologies, this invention solves the issue of large area occupation caused by inclined conveyor belt transport, which can hinder construction, especially when users are bricklaying. Users need to stand on a scaffold while laying bricks and simultaneously removing transported bricks. Since the scaffolds used for bricklaying are generally small, they cannot hold too many bricks. Bricks can only be placed in the receiving slot after the lifting lever removes bricks, potentially requiring frequent conveyor belt starts, which affects transport efficiency and is impractical. It also cannot adjust the brick transport according to the user's needs. Furthermore, this device, and some existing technologies, require workers to continuously place bricks into the receiving slot and remain on the device until no more bricks are needed. When bricks are transported one by one to the top, they cannot automatically stack in the unloading hopper; only a limited number of bricks can be placed for workers on the upper scaffold to receive. If workers fail to remove bricks from the unloading hopper in time, subsequent bricks may not be transported smoothly. Therefore, this invention provides a high-efficiency brick-delivering device for construction.

[0015] Preferably, support plates are fixedly connected to the top of each end of the two fixed columns. The first winch and the second winch are fixedly installed on the top of the support plates. The first winch and the second winch are symmetrically arranged. A top plate is fixedly connected to the top of the fixed column. A set of pulleys is fixedly connected to both ends of the top of the top plate. The pulleys cooperate with the wire rope. The distance between the bottom of the top plate and the top of the through groove is greater than the distance between the top of the operating platform and the top of the first winch.

[0016] Preferably, a limiting plate is fixedly connected to the bottom of the storage basket, and a connecting rod is fixedly connected to the side of the limiting plate near the fixed column. A roller is provided at the end of the connecting rod away from the limiting plate and is located in a through groove. The roller is in rolling contact with the inner wall of the fixed column. A base is fixedly connected to the bottom of the fixed column. Sensors are provided at the bottom of the limiting plate and the top of the connecting rod. The sensor at the bottom of the limiting plate cooperates with the top of the base, and the sensor at the top of the connecting rod cooperates with the bottom of the operating table.

[0020] The beneficial effects of this invention are:

[0021] (1) The high-efficiency brick-carrying device for building construction described in this invention uses two gears of the lifting mechanism to cooperate with the transmission component and the rack and pinion assembly, and with the fixed column, to drive the operating platform to move vertically up and down along the fixed column. The operating platform can transport construction workers and some bricks to the top. During use, there is no need to frequently start the operating platform to raise and lower it. Only when needed, the auxiliary mechanism is started to control the steel wire rope to pull the storage basket to complete the batch delivery of bricks. The advantage is that when carrying out wall construction, workers do not need to stay by the device all the time. They only need to replenish the bricks in the storage basket on time and in the required amount, which improves the labor efficiency of workers on the construction site and avoids long waiting times. The operating platform can also serve as a transfer station for brick transportation and can also be used as an operating platform when building walls. The operation on the operating platform is not affected when transporting bricks, which improves the practicality of the device.

[0022] (2) The efficient brick delivery device for building construction described in this invention can control the descent of the storage basket by a controller and the lifting of the storage basket by a control switch when bricks need to be replenished. With the use of a sensor, the first winch or the second winch will automatically stop working after the sensor comes into contact with the object, so that the winding and unwinding of the wire rope can automatically match the stopping height of the storage basket, avoiding the wire rope from bending and falling off the pulley due to excessive slack, thus improving the safety of the device.

[0023] (3) The efficient brick-passing device for building construction described in this invention has a fixed railing and a movable railing to improve the safety of construction. The connecting rod makes the storage basket always move vertically. When the storage basket is raised to a certain height, its top abuts against the movable railing, causing the movable railing to slide upward and preventing the movable railing from obstructing the workers from taking bricks out of the storage basket.

[0035] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0036] like Figure 1-9 As shown, the high-efficiency brick-passing device for building construction according to the present invention includes the following embodiments:

[0037] Example 1:

[0038] A high-efficiency brick-passing device for building construction includes a fixed column 2, a through groove 21 is opened in the fixed column 2, a lifting mechanism 6 is movably connected in the through groove 21, an operating platform 3 is fixedly connected above the lifting mechanism 6, fixed railings 4 are fixedly connected on opposite sides of the operating platform 3, and an auxiliary mechanism 7 is fixedly installed on the top of the two fixed railings 4.

[0039] The auxiliary mechanism 7 includes a first winch 73 and a second winch 74 arranged symmetrically. The first winch 73 and the second winch 74 are fixedly installed on the top of the fixed railing 4. Steel wire ropes 72 are fixedly connected to the first winch 73 and the second winch 74 respectively. A storage basket 75 is fixedly connected to one end of the steel wire rope 72 away from the first winch 73 and the second winch 74 respectively.

[0040] The lifting mechanism 6 includes a drive shaft 65 that is slidably connected to the fixed column 2. Two sets of fixed blocks 66 are fixedly connected to the bottom of the operating platform 3. A rotating shaft 67 is rotatably connected between each set of fixed blocks 66. A transmission assembly 64 is provided on the outside of the drive shaft 65 and the rotating shaft 67. A first gear 61 and a second gear 62 are fixedly connected to the two rotating shafts 67 respectively. The first gear 61 and the second gear 62 are respectively meshed with a rack assembly 63.

[0041] During operation, the workers enter the operating platform 3, where the fixed railings 4 on both sides provide some protection. By activating the lifting mechanism 6 and auxiliary mechanism 7, the drive shaft 65, under the action of the transmission component 64, causes the first gear 61 and the second gear 62 to move on the meshing rack component 63. The rotating shaft 67, fixedly connected to the first gear 61 and the second gear 62, is rotatably connected to the fixed block 66. Therefore, as the first gear 61 and the second gear 62 move along the rack component 63, they also drive the operating platform 3, fixedly connected to the fixed block 66, to move vertically on the fixed column 2, thus raising or lowering the operating platform 3. Workers can directly stand on the operating platform 3 to perform bricklaying work. At the same time, the storage basket 75 is also pulled upwards by the wire rope 72 under the action of the two winches. Some bricks can also be placed on the operating platform 3 and lifted to a higher position along with the workers, also serving a certain function of brick transportation. When the lifting mechanism 6 raises the operating platform 3 to the desired height, the lifting mechanism 6 is closed, and the workers can resume work. Workers can directly perform bricklaying work on the operating platform 3. When the bricks on the operating platform 3 are about to run out, the auxiliary mechanism 7 can be used to release the steel wire ropes 72 of the two winches, thereby lowering the storage basket 75. The left winch controls the left storage basket 75, and the right winch controls the right storage basket 75. After the workers below put the bricks into the storage basket 75, the winches will lift the storage basket 75 again, and the workers on the operating platform 3 will receive the bricks. If the bricks are transported solely by the operating platform 3, the platform 3 needs to be raised and lowered repeatedly during transportation, which affects the construction efficiency of the workers on the operating platform 3. Moreover, if too many bricks are transported on the operating platform 3, the weight will be too great, which will put too much pressure on the operating platform 3 and reduce safety. Therefore, the auxiliary mechanism 7 is used to replenish the bricks in batches from the height, which improves the safety of the workers on the operating platform 3. Furthermore, the operating platform 3 is not affected when replenishing bricks, and the workers can continue to work, thus improving construction efficiency.

[0042] In this embodiment, a connecting column 610 is fixedly connected to the inner wall of the fixed column 2. The first gear 61 and the second gear 62 are centrally symmetrically arranged. The first rack 631 and the second rack 632 are respectively meshed on the same side of the first gear 61 and the second gear 62. The first rack 631 is fixedly connected to one side of the connecting column 610, and the second rack 632 is fixedly connected to the inner wall of the fixed column 2. The first rack 631 and the second rack 632 are arranged in parallel and the tooth direction is consistent.

[0043] The transmission assembly 64 includes a sprocket 641 fixedly connected to the outside of the drive shaft 65 and the rotating shaft 67. The two rotating shafts 67 are respectively connected to the drive shaft 65 by chains 642, and the chains 642 cooperate with the sprocket 641.

[0044] A drive motor 69 is rotatably connected to the end of the drive shaft 65 away from the connecting column 610. A support frame 68 is fixedly connected to the bottom of the drive motor 69. The top of the support frame 68 is fixedly connected to the bottom of the operating table 3.

[0045] The operating table 3 is slidably engaged with the fixed column 2. A first sliding groove 22 is provided on one side of the fixed column 2. The first sliding groove 22 is connected to the through groove 21. The drive shaft 65 passes through the first sliding groove 22 and is slidably connected to the first sliding groove 22. The first sliding groove 22 is opposite to the connecting column 610.

[0046] During operation, the drive motor 69 drives the drive shaft 65 to rotate. Sprockets 641 are installed on the outer side of the drive shaft 65 and the outer sides of the two rotating shafts 67. Therefore, when the drive shaft 65 rotates, the two rotating shafts 67 rotate under the action of the chain 642, thereby causing the first gear 61 and the second gear 62, which are fixedly connected to the rotating shafts 67, to rotate. The two sets of transmission components 64 are staggered and both are powered by the drive shaft 65. At this time, the drive shaft 65 and the two rotating shafts 67 move in the same direction. The first rack 631 and the second rack 632 mesh with the same side of the first gear 61 and the second gear 62, respectively. Therefore, the first gear 61 and the second gear 62 mesh with the rack... The moving directions on component 63 are consistent, either vertically upward or vertically downward simultaneously. The first rack 631 is fixedly connected to the connecting column 610, the connecting column 610 is fixedly connected to the inner wall of the fixed column 2, and the second rack 632 is fixedly connected to the inner wall of the fixed column 2. Therefore, when the first gear 61 and the second gear 62 move on the rack assembly 63, they drive the operating table 3 to move up and down along the fixed column 2. The assembly of the two sets of gears and racks can increase the stability of the lifting and lowering of the operating table 3. The drive motor 69 provides a power source for the drive shaft 65. Under the action of the support frame 68, the drive motor 69 moves with the operating table 3, driving the drive shaft 65 to slide up and down in the first slide groove 22.

[0047] In this embodiment, support plates 42 are fixedly connected to the top of both ends of the two fixed columns 4 respectively. The first winch 73 and the second winch 74 are fixedly installed on the top of the support plates 42. The first winch 73 and the second winch 74 are symmetrically arranged. The top of the fixed column 2 is fixedly connected to the top plate 9. A set of pulleys 71 are fixedly connected to both ends of the top of the top plate 9. The pulleys 71 cooperate with the wire rope 72. The distance between the bottom of the top plate 9 and the top of the through groove 21 is greater than the distance between the top of the operating platform 3 and the top of the first winch 73.

[0048] A limiting plate 76 is fixedly connected to the bottom of the storage basket 75. A connecting rod 77 is fixedly connected to the side of the limiting plate 76 near the fixed column 2. A roller 78 is provided at the end of the connecting rod 77 away from the limiting plate 76 and is located in the through groove 21. The roller 78 is in rolling connection with the inner wall of the fixed column 2. A base 1 is fixedly connected to the bottom of the fixed column 2. Sensors 79 are provided at the bottom of the limiting plate 76 and the top of the connecting rod 77. The sensor 79 at the bottom of the limiting plate 76 cooperates with the top of the base 1, and the sensor 79 at the top of the connecting rod 77 cooperates with the bottom of the operating table 3. The horizontal height of the limiting plate 76 is the same as the horizontal height of the connecting rod 77.

[0049] A controller 8 is fixedly installed on one side of each of the two fixed railings 4. Control switches 710 are fixedly connected to the outer walls of the two storage baskets 75 respectively. The controller 8 is electrically connected to the lifting mechanism 6 and the auxiliary mechanism 7 respectively. The two control switches 710 are electrically connected to the first winch 73 and the second winch 74 respectively. The controller 8 and the control switches 710 are both electrically connected to the sensor 79.

[0050] During operation, the top plate 9 can be connected to the wall via fasteners to increase the stability of the device. The controller 8 is fixedly installed on one side of the fixed railing 4, facilitating operation when workers enter the operating platform 3. The controller 8 is equipped with buttons to control the lifting mechanism 6, as well as buttons to control the auxiliary mechanisms 7 on both sides of the operating platform 3. Control switches 710 are installed on the outer walls of the two storage baskets 75, allowing control of the auxiliary mechanisms 7 via dual-control switches. The first winch 73 and the second winch 74 rise or fall along with the fixed railing 4, which is fixedly connected to the operating platform 3. When the operating platform 3 rises, the two winches also move upwards, coordinating with the sliding mechanism above the top plate 9. Wheel 71 winds up wire rope 72, lifting storage basket 75 to the top. When bricks need to be added, the auxiliary mechanism 7 is controlled via a button on controller 8, causing storage basket 75 to descend to the ground. When sensor 79 at the bottom of limit plate 76 contacts the upper surface of base 1, the corresponding winch stops releasing wire rope 72, allowing workers on the ground to place bricks into storage basket 75. After replenishing storage basket 75, workers below press control switch 710 to raise storage basket 75. When storage basket 75 rises to a certain height, limit plate 76 abuts against operating platform 3, limiting the lifting height of storage basket 75, thus transporting storage basket 75 to the top. At the same time, the limit plate 76 remains below the operating platform 3, facilitating workers on the operating platform 3 to retrieve bricks from the storage basket 75. Simultaneously, when the limit plate 76 contacts the bottom of the operating platform 3, the sensor 79 at the top of the connecting rod 77 also contacts the bottom of the operating platform 3, causing the winch opposite to it to stop operating, thus stopping the storage basket 75 from moving. The dual-control switch setting of the auxiliary mechanism 7 improves usability; workers above only need to control the button on the controller 8 to continue construction work. The storage basket 75 automatically stops when it reaches the bottom, eliminating the need for constant monitoring. When workers below replenish the storage basket 75 with bricks, pressing the control switch 710 will raise the storage basket 75. When the sensor 79 on the connecting rod 77 contacts the operating platform 3, the rise of the storage basket 75 automatically stops, improving practicality. When the storage basket 75 rises or falls, the other end of the connecting rod 77, which is fixedly connected to it, moves on the fixed column 2. The roller 78 at the end of the connecting rod 77 rolls on the inner wall of the fixed column 2, reducing friction. The connecting rod 77 restricts the displacement of the storage basket 75, so that it always maintains vertical movement when pulled by the wire rope 72. The distance between the bottom of the top plate 9 and the top of the through groove 21 is greater than the distance between the top of the operating platform 3 and the top of the first winch 73. Therefore, when the operating platform 3 rises to its maximum extent, the tops of the two winches at the top of the fixed railing 4 will not collide with the top plate 9.

[0051] Example 2:

[0052] Based on embodiment 1, this embodiment has a second sliding groove 41 on the outer side of both ends of the two fixed rails 4, and a movable rail 5 connecting the two fixed rails 4. The movable rail 5 is slidably connected to the second sliding groove 41, and the length of the second sliding groove 41 is greater than the height of the movable rail 5. The sensor 79 at the bottom of the movable rail 5 cooperates with the top of the storage basket 75.

[0053] The distance between the limiting plate 76 and the fixed post 2 is less than the distance between the storage basket 75 and the fixed post 2, and the limiting plate 76 cooperates with the operating table 3;

[0054] During operation, the work platform 3 is surrounded by two fixed railings 4 and two movable railings 5, improving the safety of construction on the work platform 3. When the auxiliary mechanism 7 controls the storage basket 75 to rise to a certain height, the top of the storage basket 75 abuts against the bottom of the movable railing 5. During the upward movement, the movable railing 5 is pushed upward, allowing it to slide on the fixed railings 4 until the limiting plate 76 and connecting rod 77 at the bottom of the storage basket 75 abut against the bottom of the work platform 3, at which point the storage basket 75 stops moving upward. At this time, the movable railing 5 moves to its maximum height on the fixed railings 4, and the workers on the work platform 3 will not be obstructed when taking bricks from the storage basket 75 due to the movable railing 5. While improving safety, it avoids obstructing the addition of bricks to the auxiliary mechanism 7. Since the distance between the limiting plate 76 and the fixed column 2 is less than the distance between the storage basket 75 and the fixed column 2, the connecting rod 77 limits the movement angle of the storage basket 75. If the connecting rod 77 is used directly to limit the rise of the storage basket 75, it may cause excessive pressure on the connecting rod 77 and damage it. Therefore, the limiting plate 76 is used to limit the rise of the storage basket 75. At the same time, since the length of the second slide 41 is greater than the height of the movable rail 5, when the movable rail 5 slides to its maximum height, its top will not contact the first winch 73 or the second winch 74.

[0055] Working principle: During use, a fixing device can be installed above the top plate 9 to fix it to the wall, increasing the stability of the device. The construction worker enters the operating platform 3 and starts the lifting mechanism 6 and auxiliary mechanism 7 through the controller 8. The drive shaft 65, with the cooperation of the sprocket 641 and chain 642, causes the first gear 61 and the second gear 62 to move on the rack assembly 63 that meshes with it, driving the operating platform 3 to move vertically on the fixed column 2, realizing the lifting or lowering of the operating platform 3. The worker can stand directly on the operating platform 3 to carry out the wall construction work. At the same time, the storage basket 75 is also pulled to the top by the wire rope 72 under the action of the winch assembly. Some bricks can also be placed on the operating platform 3 and lifted to a high place with the worker, which also plays a certain role in brick transportation, and at the same time, it is used as a wall construction platform.

[0056] When the bricks on the operating platform 3 are about to run out, the winch assembly can be controlled via the auxiliary mechanism 7 to loosen the wire rope 72 in conjunction with the pulley 71, causing the storage basket 75 to descend. When the sensor 79 at the bottom of the limit plate 76 contacts the base 1, the winch assembly stops operating. After the worker below puts the bricks into the storage basket 75, the winch assembly is then lifted by the control switch 710. When the basket is lifted to a certain height, the top of the storage basket 75 contacts the bottom of the movable rail 5, causing the movable rail 5 to slide upward. When the sensor 79 above the connecting rod 77 contacts the bottom of the operating platform 3, the winch assembly stops operating, and the worker on the operating platform 3 receives the bricks. The auxiliary mechanism 7 replenishes the bricks in batches from the higher position, improving the safety of the worker on the operating platform 3. Furthermore, the operating platform 3 is not affected when replenishing bricks, and the worker can continue to work, thus improving construction efficiency. At the same time, the dual-control switch setting of the controller 8 and the control switch 710 used to control the auxiliary mechanism 7 also improves the practicality of the device.

[0057] The first winch 73 and the second winch 74 are respectively equipped with pulleys 71, wire ropes 72, storage baskets 75, limit plates 76 and connecting rods 77. They can be used simultaneously or separately without interference, depending on the actual situation.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by the present invention.
