Description

Technical Field

[0001] The invention relates to the technical field of hoisting machines, and in particular to a stable hoisting machine for building materials. Background Art

[0002] A crane refers to a multi-action lifting machinery that can vertically lift and horizontally move heavy objects within a certain range. At construction sites, cranes are often needed to lift construction materials and quickly move materials from one place to another, which can save manpower and time and improve work efficiency.

[0003] The yoke is provided with a plurality of lifting gears, and the lifting gears are provided with a plurality of lifting gears, and the plurality of lifting gears are provided with a plurality of lifting gears, and the plurality of lifting gears are provided with a plurality of lifting gears.

[0004] However, although the above patent solution has made improvements in improving lifting safety, there are still some potential problems: 1. When the drive motor is running, especially after long-term use, the internal bearing may become loose due to mechanical vibration, or the fit between the bearing and the end cover may become loose due to repeated disassembly and assembly. These problems will cause the motor to run out of sync and affect the stability of the output shaft.

[0005] 2. When hoisting materials for horizontal rotation and transportation, if the drive motor fails, the unstable state of the output shaft will aggravate the shaking of the materials.

[0006] 3. External environmental factors, such as strong winds, may also interfere with the stable operation of the crane, causing unexpected rapid rotation of the crane bracket, posing a safety hazard to surrounding personnel, and it is difficult to quickly stabilize the crane with manpower alone.

[0007] Based on this, in order to solve the above-mentioned technical defects, a stable hoisting machine for building materials is now proposed. Summary of the invention

[0008] In order to overcome the above-mentioned disadvantages, the present invention provides a building material stabilizing hoisting machine.

The top of the base frame is connected to the column, and the rotating frame is rotatably connected to the column. The left side of the rotating frame is connected to the connecting frame, and the driving motor is installed on the right side of the upper part of the column. The coupling is connected to the output shaft of the driving motor, and the pinion is connected to the coupling. The right side of the connecting frame is rotatably connected to the rotating shaft, and the lower side of the rotating shaft is also connected to the pinion. The lower part of the rotating frame is connected to the large gear, and the large gear is meshed with the two small gears. The connecting frame is provided with a lifting assembly. The lifting machine also includes a disc, a centrifugal block, a clamping column, a reset spring and a clamping assembly.

Reset springs are connected between the centrifugal blocks and the inside of the disc, and the position of the connecting frame located outside the disc is connected to the clamping column along the annular interval, and the rotating frame is provided with a clamping assembly.

[0010] Optionally, the centrifugal block is in contact with the clamping column, and the disc rotates at a high speed. The centrifugal block will be affected by the centrifugal force and move out from the inside of the disc, and will collide with the clamping column to slow down the disc.

The lifting main unit is installed on the left side of the connecting frame, the top of the rotating frame is rotatably connected to the roller, and the upper right side of the rotating frame is also rotatably connected to the roller. The wire rope is wound around the lifting main unit, and the tail end of the wire rope is passed around the two rollers.

[0012] Optionally, the clamping assembly includes a clamping ring, a clamping block, a clamping spring and an auxiliary assembly. A clamping ring is connected to the top of the column, clamping grooves are evenly opened on the outside of the clamping ring, and clamping blocks are evenly and slidingly connected to the inside of the clamping ring. A clamping spring is connected between the clamping block and the clamping ring, and the clamping ring is clamped in cooperation with the clamping groove. An auxiliary assembly is provided on the rotating frame.

[0013] Optionally, the auxiliary component includes a handle, a lower pressure frame, a connecting rod, a disc spring and a conical block, the handle is connected to the right side of the connecting frame, the lower pressure frame is rotatably connected to the handle, the lower part of the rotating frame is slidably connected to the conical block, the disc spring is connected between the conical block and the inside of the rotating frame, the conical block is symmetrically connected to the connecting rod, the connecting rod passes through the rotating frame and is rotatably and slidably connected to the rotating frame, the lower pressure frame is slidably connected to the two connecting rods, and the conical block is in contact with the clamping block.

[0014] Optionally, the inner side surface of the clamping block is in the shape of an inclined surface, which fits the conical surface of the conical block, and the downward movement of the conical block can push the clamping block to move outward.

[0015] Optionally, the lifting machine also includes a limit rod, a sleeve, a stabilizing spring and a push rod. The limit rod is connected to the position below the right roller on the right side of the rotating frame. The limit rod is hollow inside, and a sleeve is slidably connected to the limit rod. A stabilizing spring is connected between the sleeve and the limit rod. After the tail end of the wire rope passes around the two rollers, it will pass through the limit rod and the sleeve. A push rod is connected to the position below the sleeve on the wire rope, and the push rod is in contact and fit with the sleeve.

[0016] Optionally, the lifting machine also includes a slide rail, a support rod, a reinforcement rod and a pulley frame. The outer side of the base frame is connected to an arc-shaped slide rail, the bottom of the connecting frame is connected to a support rod, the support rod is connected to a reinforcement rod for improving the stability of the rotating frame, the bottom of the reinforcement rod is connected to a pulley frame, and the pulley frame is slidably engaged with the slide rail.

[0017] Compared with the prior art, the present invention has the following advantages: 1. Centrifugal braking system: Existing technology: In traditional designs, when an abnormality occurs in the output shaft of the drive motor or an external force (such as wind) causes the rotating frame to rotate unexpectedly, there is a lack of an effective instant braking mechanism, which may cause the equipment to lose control and pose a safety hazard.

[0018] Improvement effect: By utilizing the difference in the number of teeth of the large gear and the small gear, the disc and the centrifugal block can be accelerated to rotate and generate centrifugal force under abnormal circumstances. The centrifugal block moves outward under the action of centrifugal force and is captured by the clamping column. This mechanism can quickly slow down the disc rotation speed and stop the uncontrolled rotation of the rotating frame in time, thereby protecting the operators from injury and significantly improving the safety of equipment use.

[0019] 2. Wire rope reinforcement and stabilization system: Prior art: In hoisting operations, simply relying on the strength of the wire rope itself is often unable to completely suppress the shaking of the wire rope during the hoisting process. Especially when hoisting heavy objects, the stability of the wire rope directly affects the transportation efficiency and safety of building materials.

[0020] Improvement effect: The introduction of the limit rod and sleeve structure on the wire rope can not only enhance the structural stability of the wire rope, but also effectively reduce the vibration and swing of the wire rope during lifting operations, ensure the smooth transportation of building materials during the lifting process, and improve the efficiency and safety of the lifting operation.

[0021] 3. Turret locking and unlocking mechanism: Prior art: The conventional locking method of the rotating frame may be inconvenient to operate or the locking may not be secure, especially when the working and static states are frequently switched, the locking may fail or the unlocking may be difficult.

[0022] Improvement effect: A mechanism for linking the lower pressure frame with the conical block is designed. The clamping block and the clamping ring can be separated by simply rotating the lower pressure frame downward, allowing the rotating frame to rotate freely to facilitate the transportation of materials. After releasing the lower pressure frame, the clamping block automatically resets and clamps the clamping ring to ensure that the rotating frame remains stable in the non-working state, effectively preventing accidental rotation, simplifying the operation process, and enhancing the stability and reliability of the equipment.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Embodiment 1: A building material stabilizing hoisting machine, such as Figure 1-Figure 10As shown, it includes a base frame 1, a column 101, a rotating frame 102, a connecting frame 103, a driving motor 201, a coupling 202, a rotating shaft 203, a pinion 204, a large gear 205, a disc 301, a centrifugal block 302, a clamping column 303, a reset spring 304, a lifting component and a clamping component.

A disk 301 located inside the connecting frame 103 is connected to the top of the rotating shaft 203. Three centrifugal blocks 302 are evenly and slidably connected inside the disk 301. Reset springs 304 are connected between the centrifugal blocks 302 and the inside of the disk 301. Three clamping columns 303 are connected along the annular interval at the position outside the disk 301 in the connecting frame 103. The centrifugal blocks 302 are in contact with the clamping columns 303. When the disk 301 rotates at a high speed, the centrifugal blocks 302 will be affected by the centrifugal force and move out from the inside of the disk 301, and will collide with the clamping columns 303, thereby slowing down the disk 301. A hoisting assembly is provided on the connecting frame 103, and a clamping assembly is provided on the rotating frame 102.

[0037] like Figure 1-Figure 2 As shown, the lifting assembly also includes a lifting main unit 104, rollers 105 and wire ropes 106. The lifting main unit 104 is installed on the left side of the connecting frame 103 by bolts, the top of the rotating frame 102 is rotatably connected to the roller 105, and the upper right side of the rotating frame 102 is also rotatably connected to the roller 105. The wire rope 106 is wound around the lifting main unit 104, and the tail end of the wire rope 106 is passed around the two rollers 105.

[0038] like Figure 1 and Figure 7-Figure 10 As shown, the snap-on assembly includes a snap ring 403, a snap block 407, a snap spring 408 and an auxiliary assembly. A snap ring 403 is welded on the top of the column 101. A snap groove 409 is evenly opened on the outside of the snap ring 403. Three snap blocks 407 are evenly and slidably connected on the inside of the snap ring 403. A snap spring 408 is connected between the snap blocks 407 and the snap ring 403. The snap ring 403 is snap-fitted with the snap groove 409 to fix the rotating frame 102. An auxiliary assembly is provided on the rotating frame 102.

[0039] like Figure 1 and Figure 7-Figure 10As shown, the auxiliary component includes a handle 401, a lower pressure frame 402, a connecting rod 404, a disc spring 405 and a conical block 406. The handle 401 is welded on the right side of the connecting frame 103. The lower pressure frame 402 is rotatably connected to the handle 401. The lower part of the rotating frame 102 is slidably connected to the conical block 406. The disc spring 405 is connected between the conical block 406 and the inside of the rotating frame 102. The conical block 406 is symmetrically connected to the connecting rod 404 front and back. The connecting rod 404 passes through the rotating frame 102 and is rotatably and slidably connected to the rotating frame 102. The lower pressure frame 402 is slidably connected to the two connecting rods 404. The conical block 406 is in contact with and cooperates with the clamping block 407. The inner side surface of the clamping block 407 is inclined and fits the conical surface of the conical block 406. The downward movement of the conical block 406 can push the clamping block 407 to move outward.

[0040] The wire rope 106 can be wound up by the hoisting main machine 104, and the hook can be connected to the tail end of the wire rope 106, and the building material can be hoisted by the hook. The hoisting main machine 104 winds up the wire rope 106 to lift the building material, and the roller 105 limits the wire rope 106, and then the rotating frame 102 is driven by the driving motor 201 to rotate horizontally, so that the building material can be transported to the specified position. During the specific operation, the material is first fixed on the hook of the wire rope 106, and then the hoisting main machine 104 is started to wind up the wire rope 106 to lift the material. After the material is lifted off the ground to a suitable height, the handle 401 can be held with one hand, and the lower pressure frame 402 can be rotated downward with the other hand. The lower pressure frame 402 will push the connecting rod 404 to move upward, thereby driving The conical block 406 moves upward, and the disc spring 405 is compressed. Initially, the clamping spring 408 is in a compressed state. The conical block 406 moves upward and will no longer resist the clamping block 407. The clamping block 407 will move inward under the reset action of the clamping spring 408, and will no longer be stuck in the clamping slot 409. The staff continues to press the lower pressing frame 402 with their hands, and then starts the driving motor 201. The rotation of the output shaft of the driving motor 201 will drive the small gear 204 on the right to rotate through the coupling 202, and then drive the large gear 205 to rotate. The large gear 205 drives the small gear 204 on the left and the rotating shaft 203 to rotate, and the disc 301 and the centrifugal block 302 will rotate along with it. The rotation of the large gear 205 also drives the rotating frame 102 to rotate, and the rotating frame 102 connected to the rotating frame 102 All parts will rotate, and the material will rotate horizontally with the rotating frame 102. After the material is transported to the specified position, the drive motor 201 is turned off, and then the lower pressure frame 402 is released. The conical block 406 will move downward and reset under the reset action of the disc spring 405, driving the connecting rod 404 to move downward, and the connecting rod 404 will push the lower pressure frame 402 to rotate and reset upward. The downward movement of the conical block 406 will push the clamping block 407 to move outward, compressing the clamping spring 408, and the clamping block 407 will be clamped with the clamping groove 409, thereby fixing the rotating frame 102. The staff can unwind the wire rope 106 through the hoisting host 104 and put the material on the ground to complete the hoisting of the material. During the use of this device, if the drive motor 201 When the bearing is damaged and the output shaft is unstable, after starting the drive motor 201, the output shaft is unstable, resulting in uneven rotation or additional vibration. When the building material has a large windward area, the wind can generate enough torque to affect the rotating frame 102 and rotate quickly, which will cause the large gear 205 to rotate and drive the small gear 204 to rotate. Because the large gear 205 has more teeth than the small gear 204, the small gear 204 will rotate at a high speed due to the large gear 205, thereby driving the rotating shaft 203 to rotate, and the disc 301 and the centrifugal block 302 will rotate with it. When the disc 301 rotates at a high speed, centrifugal force will be generated, causing the centrifugal block 302 in the disc 301 to move outward under the influence of the force, and the reset spring 304 will be stretched, and the centrifugal block 302 will contact the column 303.The clamping column 303 will resist the centrifugal block 302, decelerating the disc 301 and reducing the rotation speed of the disc 301 to prevent the rotating frame 102 from continuing to rotate and causing harm to the staff. After the rotating frame 102 speed is reduced, the disc 301 no longer rotates at a high speed, and the centrifugal block 302 is in a relaxed state. It will move inward and reset under the reset action of the reset spring 304, and the staff can repair the drive motor 201. Such a design ensures the safety of the device and protects the life safety of the staff to a great extent. When the drive motor 201 is in normal use, the rotating shaft 203 rotates with the disc 301 and the centrifugal block 302. The disc 301 rotates slowly, and no centrifugal force will occur. The centrifugal block 302 will not affect the normal rotation of the disc 301.

[0041] Embodiment 2: Based on embodiment 1, Figure 1 and Fig.11 As shown, the hoisting machine also includes a limit rod 501, a sleeve 502, a stabilizing spring 503 and a push rod 504. The limit rod 501 is connected to the position below the right roller 105 on the right side of the rotating frame 102. The limit rod 501 is hollow inside, and the sleeve 502 is slidably connected to the limit rod 501. A stabilizing spring 503 is connected between the sleeve 502 and the limit rod 501. The tail end of the wire rope 106 will pass through the limit rod 501 and the sleeve 502 after passing around the two rollers 105. The push rod 504 is connected to the position below the sleeve 502 on the wire rope 106. The push rod 504 is in contact with the sleeve 502. The wire rope 106 hoists the material upward and moves with the push rod 504, and the push rod 504 pushes the sleeve 502 to move upward.

[0042] The steel wire rope 106 passes through the limit rod 501 and the sleeve 502. The sleeve 502 and the limit rod 501 can improve the stability of the steel wire rope 106 and reduce the possibility of the steel wire rope 106 swinging due to external force when hoisting materials. When the steel wire rope 106 is reeled and moved upward, it moves upward with the push rod 504, and the push rod 504 will push the sleeve 502 upward to compress the stabilizing spring 503. When the steel wire rope 106 is unreeled and moved downward, it moves downward with the push rod 504, and the push rod 504 no longer resists the sleeve 502. The sleeve 502 will move downward due to the resetting of the stabilizing spring 503, which will not affect the normal use of the steel wire rope 106.

[0043] like Figure 1As shown, the hoisting machine also includes a slide rail 701, a support rod 702, a reinforcement rod 703 and a pulley frame 704. The outer side of the base frame 1 is connected with an arc-shaped slide rail 701 by bolts, the bottom of the connecting frame 103 is connected with a support rod 702, and a reinforcement rod 703 for improving the stability of the rotating frame 102 is welded on the support rod 702. The bottom of the reinforcement rod 703 is connected with a pulley frame 704, and the pulley frame 704 is slidably engaged with the slide rail 701. The rotating frame 102 rotates with the connecting frame 103, and the reinforcement rod 703 can drive the pulley frame 704 to slide along the slide rail 701.

[0044] When the rotating frame 102 rotates along the column 101, it will drive the connecting frame 103 to rotate, and the connecting frame 103 will drive the support rod 702 and the reinforcement rod 703 to rotate, and then drive the pulley frame 704 to rotate. The pulley frame 704 will slide along the slide rail 701. When hoisting materials, one side of the device is subjected to greater force, and the reinforcement rod 703 can stabilize the connecting frame 103.

[0045] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
