Description

Technical Field

[0001] The utility model relates to the technical field of anti-slip pile hole digging construction, in particular to an anti-slip pile manual hole digging and lifting device which is easy to operate and safe. Background Art

[0002] Anti-slide piles are piles that pass through the landslide body and deep into the sliding bed. They are used to support the sliding force of the sliding body and stabilize the slope. They are suitable for shallow and medium-thick landslides and are a major anti-slide treatment measure.

[0003] When carrying out anti-slip pile construction, mechanical digging or manual digging is required. Manual digging is convenient and fast, and does not require large-scale mechanical equipment. Bored piles have strong earthquake resistance and low cost. Manual holes are generally divided into rectangular holes and circular holes, and workers are required to transport the soil in the pile hole out of the pile hole. What is generally used in conjunction with manual digging is a hoist, that is, a base frame with a winch installed on the base frame. The hook is placed in the pile hole through a wire rope and pulley guide, and the worker puts the soil into a bucket and transports it up through the winch.

[0004] When the hoist is in use, it extends to the top of the pile hole through the hanger. Workers dig holes in the pile holes, and workers above cooperate to transport soil blocks. After the soil blocks are filled, they are lifted up from the pile hole. If the pile hole is relatively large, the hanger will be placed in the middle of the pile hole, rather than the edge of the pile hole. First, it prevents the bucket from colliding with the wall of the pile hole during lifting, causing the bucket and soil blocks to fall. Second, when digging holes at the far end, after the bucket is full, it still needs to be manually lifted for a distance, so the hanger is generally placed above the middle of the pile hole. However, the hanger generally only has the function of rotation. After each lifting, the hanger can only be rotated 90°, then walk to the end of the hanger to remove the bucket and pour out the soil blocks, then walk back to the original place to reverse the hanger 90° and transport the bucket down, which brings great inconvenience to the operator above. Some hoists also solve the mobility problem by installing a transversely movable electric hoist, but the electric hoist is expensive and increases the counterweight at the end of the hanger, which requires a lot of extra counterweights on the base frame, otherwise it will cause greater safety hazards.

[0005] In addition, no matter whether the bucket is being raised or lowered, if there are workers working below at this time, especially when the bucket is being raised, the construction workers below only have a safety helmet as a protective measure. If the bucket as a whole or the soil inside the bucket falls and hits the workers, it will bring great safety hazards. Previously, the operators above would inform them by shouting. However, as the depth of the pile hole increases, coupled with the noise from various equipment at the outdoor construction site, sometimes the shouting cannot be heard clearly. Therefore, when the bucket is rising and falling, there are safety hazards to the workers directly below.

[0006] On this basis, the utility model provides an easy-to-operate and safe anti-slip pile manual hole digging and lifting device to solve the problem. Utility Model Content

A control button is provided on the control box 6, and the control box is also equipped with a control handle, which can be wired or wireless. A winch device 7 is fixed at the rear of the base frame 1, and the winch device 7 mainly includes a drive motor 20 and a winch drum. The drive motor 20 adopts a pure copper core motor. A steel wire rope 8 is wound around the winch device 7, and the steel wire rope 8 is a galvanized / oiled steel wire rope. The steel wire rope 8 is connected to a hook 9 after passing around the rear pulley 5, the middle pulley 4 and the front pulley 3 in sequence. The hook 9 is provided with an anti-falling card plate. The hanger 2 includes a transversely arranged cross frame 10 and an obliquely arranged inclined frame 11. The cross frame 10 and the oblique frame 11 are fixedly connected. A mounting groove is provided at the front end of the cross frame 10. An electric motor 12 is installed in the mounting groove. The electric motor 12 is connected to a control box. The electric motor 12 is connected to a screw rod 13. The screw rod 13 is made of thickened high-strength carbon steel and can withstand a bucket full of soil. A slide rail is provided in the mounting groove. The thread on the screw rod 13 is matched with a slider 14 slidably installed in the slide rail, and the front pulley 3 is fixed at the lower end of the slider 14.

[0028] When the bucket is lifted, the electric motor 12 is controlled to start, driving the slider 14 and the front pulley 3 to move backward, thereby driving the bucket close to the edge of the pile hole to facilitate the removal of the bucket. Conversely, the electric motor 12 is controlled to move the bucket in the opposite direction.

[0029] An embodiment is provided: the electric motor 12 and the hoisting device 7 are jointly connected to the control box, that is, when the bucket moves backward, the hoisting device 7 tightens the wire rope 8, and after the electric motor 12 stops, the hoisting device 7 stops. When the electric motor 12 moves forward, the hoisting device 7 synchronously releases the wire rope, ensuring that when the bucket moves forward and backward, the hoisting device 7 follows the tightening / releasing of the wire rope.

[0030] Another embodiment: An inclined slide groove 15 with the same inclination is provided on the inclined frame 11, and a tensioning wheel 16 is slidably installed in the inclined slide groove 15. The wire rope 8 is wound in the form of passing through the rear pulley 5, the middle pulley 4, the tensioning wheel 16, and the front pulley 3 in sequence and then connected to the hook 9. An arc plate is provided at the lower end of the tensioning wheel 16, one of which is used for allowing the wire rope 8 to pass through so that the wire rope 8 moves together when the tensioning wheel 16 moves up and down, and the other is to facilitate the fixing of the pull rod 18. A sliding hole 17 is provided at the lower end of the inclined slide groove 15, and a pull rod 18 is slidably installed in the sliding hole 17. One end of the pull rod 18 is connected to the tensioning wheel 16, and the other end of the pull rod 18 is connected to the spring 19. The other end of the spring 19 is connected to the electric telescopic rod, and the electric telescopic rod is connected to the control box.

[0031] When the electric motor 12 is started and the bucket moves backward, the electric telescopic rod synchronously pulls the tensioning wheel 16 to keep the wire rope 8 taut. When the electric motor 12 is reversed and the bucket moves forward, the electric push rod pushes the tensioning wheel 16 in the reverse direction to keep the wire rope 8 taut.

[0032] Furthermore, the hoisting device 7 mainly includes a drive motor 20, which is connected to the control box 6, and the drive motor 20 is coaxially connected to a small pulley 21, and the small pulley 21 is belt-connected to a large pulley 22 to achieve deceleration. The large pulley 22 is coaxially connected to a hoisting drum, and a steel wire rope 8 is wound around the hoisting drum. A synchronization device is provided at the front end of the steel wire rope 8 to ensure that the steel wire rope 8 is wound around the winding drum in sequence, to ensure the neatness of the wound steel wire rope 8 and to prevent random winding from causing bending damage to the steel wire rope 8.

[0033] An embodiment is provided: baffles 23 are fixed at both ends of the winch drum, and the synchronization device includes a bidirectional screw rod 24 rotatably mounted on the baffle plate 23 and located in front of the winch drum. The bidirectional screw rod 24 is a bidirectional thread with forward and reverse crosses, that is, after moving the end head, it automatically reverses through another thread. The bidirectional screw rod 24 is coaxially connected to a screw pulley 28, and the screw pulley 28 is belt-connected to a large pulley 22. The large pulley 22 is a double-groove pulley. A synchronous slider 25 is threadedly slidably mounted on the bidirectional screw rod 24. The pitch of the large pulley 22, the screw pulley 28, and the bidirectional screw rod 24 is set so that the moving speed of the synchronous slider 25 matches the winding speed. A plurality of limit rods 26 fixed on the baffle plate 23 are penetrated at the lower end of the synchronous slider 25. A through hole 27 for the wire rope 8 to pass through is opened on the synchronous slider 25. The wire rope 8 passes through the through hole 27, thereby driving the wire rope 8 to move and wind at the same time.

[0034] In order to better guide the winding of the steel wire rope 8 , two symmetrically arranged guide rollers 29 are rotatably installed at the front end of the synchronous slider 25 , and the steel wire rope 8 passes between the two guide rollers 29 after passing through the through hole.

[0035] In order to better guide the wire rope 8, two of the limit rods 26 are fixed up and down, and the wire rope 8 passes through the middle of the two limit rods 26, so that the wire rope 8 is limited in the up, down, left and right directions.

[0037] When the depth of the manual hole excavation is deep, the construction workers need to use the lifting device to enter and exit the pile hole. At this time, the workers need to use a safety belt in conjunction with the fall arrester 31 to ensure the safety of the workers.

[0038] Furthermore, a support plate 32 is fixed to the front end of the horizontal frame 1, and an infrared detector 33 is fixed to the lower end of the support plate 32. The infrared detector 33 is connected to the control box 6 to detect whether there are construction workers in the area of ​​the pile hole to prevent the bucket from falling and causing harm to the workers when it rises and falls. When someone is detected under the infrared detector 33, the infrared detector 33 will sound an alarm, and the drive motor 20 can be controlled to stop according to the set scene. The depth of manual digging will generally not exceed 20 meters in consideration of safety factors. If it exceeds 20 meters, mechanical digging is generally used. The infrared detector 33 can be selected from a certain brand, model E3K-100-R20M, material ABS, detection distance 20 meters, working 24-240V, AC and DC universal, relying on relay output, wide angle of 5°, which is suitable for deep pile holes. If the depth of the pile hole is within 12 meters, a certain brand, model MC-565R can be selected, detection angle 110°, detection distance 12 meters, working voltage DC3V 1*CR123A lithium battery.

[0039] Furthermore, a vertical frame 34 is fixed at the front end of the base frame 1, and a rotating column 35 is fixed to the upper and lower ends of the vertical frame 34. The rear ends of the horizontal frame 10 and the inclined frame 11 are provided with a sleeve 36 that rotates on the rotating column 35 to realize the rotation of the hanger.

[0040] Through the signal coordination between the electric motor 12 and the hoisting device or the signal coordination between the electric motor 12 and the electric telescopic rod, the front pulley 3 can not only move forward and backward, but also ensure that the wire rope 8 is always tightened. The infrared detector 33 detects the workers in the pile hole, so that when someone is found in the area, an alarm is issued or a signal is sent to the drive motor 20 to stop. The synchronization device allows the wire rope 8 to be wound around the hoisting drum in turn without causing compression and bending damage to the wire rope 8.
