A building material storage and dispatching device

Abstract

This utility model relates to the field of building materials technology and discloses a building materials storage and scheduling device, including two movable frames and a lasso hook. A crossbeam is fixedly connected to the center of the top of the two movable frames. Guide grooves are opened on both sides of the outer wall of the crossbeam. The lasso hook is controlled by an anti-impact mechanism to prevent the output shaft of the second motor from rotating excessively, thus avoiding the lasso hook from impacting the U-shaped frame during the winding of the steel strand and causing damage. The distance sensor can monitor the distance between the lasso hook and the U-shaped frame in time. When the lasso hook gets too close to the U-shaped frame, the PLC control module controls the extension ends of the two electric push rods to rise and pull the sleeve to make an upward linear motion, and squeeze the two inclined clamps. The two inclined clamps move synchronously in a linear motion to clamp the steel strand and prevent the steel strand from moving further through friction.

Description

Technical Field

[0001] This utility model relates to the field of building materials technology, specifically to a building materials storage and scheduling device. Background Technology

[0002] With the continued prosperity of the global construction industry, various large-scale infrastructure construction projects, commercial real estate development and residential construction are constantly advancing, and the production and use of building materials are showing an explosive growth trend. Against this background, the warehouse storage of building materials, as a key link connecting production and construction, is becoming increasingly important. Some steel is placed in warehouses, and in order to effectively move the steel, it is necessary to use gantry cranes to lift the steel.

[0003] In the field of building material warehousing and scheduling, hoisting equipment is a key tool for achieving efficient material handling. In existing technologies, common hoisting devices often use a motor-driven drum to control the lifting and lowering of the hook by winding and unwinding the steel cable. However, this method poses significant safety hazards in actual use. Due to the lack of an effective travel limiting mechanism, when the control system malfunctions or the operator misoperates, the motor may continue to rotate, causing the drum to over-wind the steel cable. This causes the hook to impact the top limiting structure at high speed. Such impacts can not only cause deformation and damage to key components such as the hook and steel cable, but in severe cases, they can even lead to the structural failure of the entire hoisting device. Especially in high-frequency operation scenarios, repeated mechanical impacts can accelerate equipment wear, significantly shorten service life, and increase maintenance costs. Therefore, those skilled in the art provide a building material warehousing and scheduling device to solve the problems mentioned in the background art. Utility Model Content

[0005] This utility model provides the following technical solution: a building material storage and scheduling device, including two movable frames and a lasso hook. A crossbeam is fixedly connected to the center of the top of the two movable frames. Guide grooves are provided on both sides of the outer wall of the crossbeam. A suspension mechanism for moving building materials is provided below the crossbeam. A drive component for driving the suspension mechanism to make linear motion is provided on the outer wall of the crossbeam. An anti-collision mechanism is provided on the outer wall of the suspension mechanism to prevent the lasso hook from hitting the top.

[0006] Preferably, the drive assembly includes a mounting frame, with three movable wheels rotatably sleeved on both sides of the inner wall of the mounting frame, and a total of six movable wheels slidably sleeved inside two guide grooves. A rack is embedded at the bottom end of the crossbeam. Two first motors are symmetrically fixedly connected to the inner side wall of the mounting frame. A drive rod is fixedly connected to the output end of each first motor. A gear that meshes with the rack is fixedly sleeved on the outer wall of the drive rod.

[0007] Preferably, a bearing frame is symmetrically fixedly connected to the inner side wall of the mounting frame away from the first motor, and the end of the drive rod away from the first motor is located inside the bearing frame and is rotatably sleeved with the bearing frame through a bearing.

[0008] Preferably, the suspension mechanism includes a top mounting frame fixedly connected to the bottom of the mounting frame. A second motor is fixedly connected to the inner bottom of the top mounting frame. A take-up roller is fixedly sleeved on the outer wall of the output shaft of the second motor. The rotating shaft of the take-up roller is rotatably sleeved with the inner side wall of the top mounting frame through a bearing. A steel strand is wound around the outer wall of the take-up roller. A connecting disc is fixedly connected to the end of the steel strand. A sling hook is sleeved on the lower bottom of the connecting disc through a steel cable.

[0009] Preferably, the start / stop control terminal of the second motor is fixedly connected to a control line, and the end of the control line away from the second motor is fixedly connected to a controller for controlling the start / stop of the second motor.

[0010] Preferably, the anti-collision mechanism includes a U-shaped frame fixedly connected to the outer wall of the top mounting bracket, an electromagnet fixedly connected to the bottom end of the U-shaped frame, a distance sensor fixedly connected to the bottom end of the U-shaped frame on one side of the electromagnet, and a magnetic block embedded in the top of the connecting plate. In the start-up state, the electromagnet and the magnetic block on the side near the U-shaped frame exert a repulsive force.

[0011] Preferably: A PLC control module is fixedly connected to the inner bottom end of the U-shaped frame; an opening for the steel strand to pass through is provided through the inner bottom end of the U-shaped frame; two rollers for guiding the steel strand are symmetrically rotated and sleeved on the inner side wall of the opening inside the U-shaped frame; support rods are fixedly connected to both sides of the opening at the inner bottom end of the U-shaped frame; a top plate is fixedly connected to the upper top of the two support rods; two oblique clamps are symmetrically slidably sleeved on the lower bottom end of the top plate; two electric push rods are symmetrically fixedly connected at a 90-degree angle between the lower bottom end of the top plate and the two oblique clamps; a sleeve is provided at the lower bottom end of the top plate; side plates are symmetrically fixedly connected to the outer side wall of the sleeve; the telescopic end of the electric push rod is fixedly connected to the center of the upper top of the side plate; and the two oblique clamps slide and sleeve inside the sleeve after they are brought together.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention incorporates an anti-impact mechanism. During use, this mechanism controls the lasso hook to prevent excessive rotation of the second motor's output shaft, which could cause the lasso hook to impact the U-shaped frame during the winding of the steel strand, thus preventing damage. A distance sensor monitors the distance between the lasso hook and the U-shaped frame. When the lasso hook gets too close to the U-shaped frame, the PLC control module raises the extension ends of the two electric push rods, pulling the sleeve upwards in a linear motion and squeezing the two inclined clamps. These clamps move synchronously in a linear motion, clamping the steel strand and using friction to prevent further movement. Simultaneously, the PLC control module activates an electromagnet. The repulsive force between the electromagnet and the magnetic block prevents the connecting disc from rising further, thus preventing the lasso hook from impacting the frame.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] Please see Figure 1 - Figure 5 As shown, this utility model provides a technical solution: a building material storage and scheduling device, including two movable frames 1 and a lasso hook 55. A crossbeam 2 is fixedly connected to the center of the upper top of the two movable frames 1. Guide grooves 3 are provided on both sides of the outer wall of the crossbeam 2. A suspension mechanism 5 for moving building materials is provided below the crossbeam 2. A drive component 4 for driving the suspension mechanism 5 to make linear motion is provided on the outer wall of the crossbeam 2. An anti-collision mechanism 6 for preventing the lasso hook 55 from hitting the top is provided on the outer wall of the suspension mechanism 5.

[0022] It should be noted that the suspension mechanism 5 is equipped with a lasso hook 55, which can accurately suspend building materials of different specifications. Together with the guide grooves 3 on both sides of the outer wall of the crossbeam 2, it ensures that the suspension mechanism 5 remains stable during linear movement. The drive component 4 is integrated into the outer wall of the crossbeam 2 and drives the suspension mechanism 5 to move quickly along the guide groove 3 through an efficient power transmission system. The anti-overload mechanism 6 innovatively adopts a dual protection mechanism of electromagnetic buffer and mechanical limit. When the lasso hook 55 approaches the upper limit of the stroke, the anti-overload mechanism 6 is automatically triggered, effectively preventing equipment overload damage.

[0023] As one implementation method in this embodiment, please refer to Figure 1 - Figure 3 As shown, the drive assembly 4 includes a mounting frame 41. Three movable wheels 42 are rotatably sleeved on both sides of the inner wall of the mounting frame 41, and a total of six movable wheels 42 are slidably sleeved inside the two guide grooves 3. A rack 47 is embedded in the lower bottom end of the crossbeam 2. Two first motors 43 are symmetrically fixedly connected to the inner side wall of the mounting frame 41. A drive rod 44 is fixedly connected to the output end of each first motor 43. A gear 45 that meshes with the rack 47 is fixedly sleeved on the outer wall of the drive rod 44. A bearing bracket 46 is symmetrically fixedly connected to the inner side wall of the mounting frame 41 away from the first motor 43. The end of the drive rod 44 away from the first motor 43 is located inside the bearing bracket 46 and is rotatably sleeved with the bearing bracket 46 through a bearing.

[0024] It should be noted that the six movable wheels 42 are respectively rotatably sleeved on both sides of the inner wall of the mounting frame 41, and are all slidably sleeved inside the two guide grooves 3. This layout allows the mounting frame 41 to move smoothly on the crossbeam 2, effectively avoiding shaking and offset during the movement, and ensuring the stability of the entire scheduling device. The rack 47 embedded at the bottom of the crossbeam 2 meshes with the gear 45 fixedly sleeved on the outer wall of the drive rod 44. The two first motors 43 are symmetrically fixed on the inner wall of the mounting frame 41, and their output ends drive the drive rod 44 to rotate, thereby driving the gear 45 to roll along the rack 47, realizing the linear movement of the mounting frame 41. This transmission method is precise and reliable, and can accurately control the moving distance and speed of the mounting frame 41. At the same time, the bearing bracket 46 symmetrically fixed on the inner wall of the mounting frame 41 away from the first motor 43 rotatably sleeves the end of the drive rod 44 away from the first motor 43 through the bearing, providing stable support for the drive rod 44 and reducing friction and vibration during rotation.

[0025] As one implementation method in this embodiment, please refer to Figure 3 and Figure 4 As shown, the suspension mechanism 5 includes a top mounting bracket 511 fixedly connected to the bottom of the mounting frame 41. A second motor 51 is fixedly connected to the inner bottom of the top mounting bracket 511. A take-up roller 52 is fixedly sleeved on the outer wall of the output shaft of the second motor 51. The rotating shaft of the take-up roller 52 is rotatably sleeved with the inner side wall of the top mounting bracket 511 through a bearing. A steel strand 53 is wound and connected to the outer wall of the take-up roller 52. A connecting disc 54 is fixedly connected to the end of the steel strand 53. A lasso hook 55 is sleeved on the bottom of the connecting disc 54 through a steel cable. A control line 56 is fixedly connected to the start and stop control end of the second motor 51. A controller 57 for controlling the start and stop of the second motor 51 is fixedly connected to the end of the control line 56 away from the second motor 51.

[0026] It should be noted that the second motor 51 is fixed to the bottom of the top mounting bracket 511. Its output shaft drives the winding roller 52 to rotate. The winding roller 52 is rotatably sleeved with the inner side wall of the top mounting bracket 511 through bearings. This structure makes the winding roller 52 rotate flexibly and stably, and can efficiently realize the winding and unwinding of the steel strand 53. The steel strand 53 is wound around the outer wall of the winding roller 52. The connecting disc 54 connected to its end and the lasso hook 55 connected by the steel cable below can be raised and lowered with the winding and unwinding of the steel strand 53, so as to flexibly lift and transport building materials and meet the storage and scheduling needs of different heights. The start and stop control end of the second motor 51 is connected to the controller 57 through the control line 56. The operator can remotely and accurately control the start and stop of the second motor 51 through the controller 57 to realize precise control of the lifting and lowering of the lasso hook 55, which greatly improves the convenience and safety of operation.

[0027] As one implementation method in this embodiment, please refer to Figure 3 - Figure 5 As shown, the anti-collision mechanism 6 includes a U-shaped frame 61 fixedly connected to the outer wall of the top mounting bracket 511. An electromagnet 63 is fixedly connected to the bottom end of the U-shaped frame 61. A ranging sensor 64 is fixedly connected to the bottom end of the U-shaped frame 61 on one side of the electromagnet 63. A magnetic block 62 is embedded in the top of the connecting plate 54. In the start-up state, the electromagnet 63 and the magnetic block 62 exert a repulsive force on the side of the U-shaped frame 61. A PLC control module 65 is fixedly connected to the bottom inner end of the U-shaped frame 61. An opening 66 is provided through the bottom inner end of the U-shaped frame 61 for the steel strand 53 to pass through. Two control steel strands 53 are symmetrically rotated and sleeved inside the U-shaped frame 61 on the inner side wall of the opening 66. The roller 661 and the inner bottom of the U-shaped frame 61 are both fixedly connected to support rods 67 on both sides of the opening 66. The top ends of the two support rods 67 are fixedly connected to a top plate 671. Two oblique clamps 69 are symmetrically slidably sleeved on the bottom end of the top plate 671. Two electric push rods 682 are symmetrically fixedly connected at a 90-degree angle between the bottom end of the top plate 671 and the two oblique clamps 69. A sleeve 68 is provided at the bottom end of the top plate 671. Side plates 681 are symmetrically fixedly connected to the outer wall of the sleeve 68. The telescopic ends of the electric push rods 682 are fixedly connected to the center of the top end of the side plates 681. The two oblique clamps 69 slide and fit inside the sleeve 68 after being brought together. It should be noted that the bringing together of the two oblique clamps 69 is for clamping and fixing the steel strand 53.

[0028] It should be noted that the distance sensor 64 is installed at the bottom of the U-shaped frame 61, which can monitor the distance between the lasso hook 55 (indirectly reflected by the magnetic block 62 on the connecting plate 54) and the U-shaped frame 61 in real time and detect potential risks of overshooting. When the distance is too close, the PLC control module 65 responds quickly and controls the extension end of the electric push rod 682 to rise, pulling the sleeve 68 to drive the two inclined clamps 69 to move synchronously in a straight line, clamping the steel strand 53 passing through the opening 66. The friction force prevents the steel strand 53 (which has a repulsive force with the magnetic block 62 on the side closer to the U-shaped frame 61) and the connecting plate 54 from rising further, effectively preventing the lasso hook 55 from overshooting. At the same time, the two rollers 661 that control the guide of the steel strand 53 rotate and engage. On the inner sidewall of opening 66, the steel strand 53 is ensured to move smoothly and wear is reduced. The cooperation between the top plate 671 and the support rod 67 provides a stable mounting platform for components such as the electric push rod 682 and the inclined clamp 69, ensuring the reliable operation of the entire anti-impact mechanism 6. The model of the distance sensor 64 can be SENST-70 (not specifically specified). A corresponding magnetic blocking plate can be installed above the connecting plate 54 around the magnetic block 62. The material of the magnetic blocking plate can be aluminum or silicon steel plate, which is used to weaken the magnetic force and effectively prevent the magnetic block 62 from attracting the steel strand 53. The electric push rod 682, the distance sensor 64 and the electromagnet 63 are all connected to the PLC control module 65 through wires to establish a control channel.

[0029] Working principle: The anti-impact mechanism 6 is set to protect the sling hook 55 from impact. During operation, the first motor 43 of the drive assembly 4 drives the drive rod 44 and gear 45 to rotate. The gear 45 meshes with the rack 47 on the crossbeam 2, causing the mounting frame 41 to move linearly along the guide groove 3 through the movable wheel 42, thereby driving the suspension mechanism 5 to move horizontally. The second motor 51 of the suspension mechanism 5 drives the winding roller 52 to rotate, which drives the connecting plate 54 and sling hook 55 to rise and fall through the steel strand 53, realizing the hoisting of building materials.

[0030] During this process, the distance sensor 64 of the anti-collision mechanism 6 monitors the distance between the connecting plate 54 and the U-shaped frame 61 in real time. When the lasso hook 55 rises excessively, causing the connecting plate 54 to approach the U-shaped frame 61, the PLC control module 65 immediately activates two-level protection: on the one hand, it controls the extension ends of the two electric push rods 682 to rise, pulls the sleeve 68 to rise through the side plate 681, and squeezes the two inclined clamps 69 to clamp the steel strand 53 inward synchronously, preventing the steel strand 53 from continuing to move through friction; on the other hand, it simultaneously activates the electromagnet 63, so that it generates a repulsive force with the magnetic block 62 on the connecting plate 54, further preventing the connecting plate 54 from rising. The mechanical clamping of the inclined clamp 69 and the magnetic repulsion of the electromagnet 63 effectively prevent the winding roller 52 from over-winding and causing the lasso hook 55 to impact the U-shaped frame 61, thus preventing equipment damage. At the same time, the steel strand 53 is guided by the roller 661 when passing through the opening 66. The support rod 67 and the top plate 671 provide stable support for the inclined clamp 69, ensuring that the anti-impact action is accurate and reliable.

[0031] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
