Description

Technical Field

[0001] The utility model belongs to the technical field of engineering construction, in particular to a prestressed pipe pile hoisting device in high-cold areas. Background Art

[0002] When carrying out engineering construction in high-cold areas, there is frozen soil due to the uniqueness of the regional climate. When constructing in frozen soil areas, in order to avoid the problem of reduced stability of the engineering foundation caused by the retreat of frozen soil due to seasonal changes, prestressed pipe piles are often used as supporting foundations in frozen soil areas. When using prestressed pipe piles, because they are prefabricated parts, they need to be used and transported specifically during the construction process. At present, when transporting prestressed pipe piles during the construction process, they are mostly transported by lifting equipment. For example, the patent document disclosed in the patent publication number CN115838114A, the patent name is a prestressed concrete pipe pile handling hoist, and the handling hoist used with the lifting equipment can lift the prestressed pipe piles. However, in the specific construction, the pipe piles are mostly constructed in a vertical erected form. The handling hoist disclosed in the above text can only transport the pipe piles. In the subsequent construction process, the construction personnel need to flip the pipe piles to a vertical posture. Because the overall volume and mass of the pipe piles are huge, it is very difficult to transfer the pipe piles and there are high construction safety risks. Utility Model Content

[0025] The base 1 includes a driving chain 11 and a plurality of slings 12; the driving chain 11 and the slings 12 are arranged with the same length, and the driving chain 11 and the plurality of slings 12 are fixedly connected at both ends of the base 1 in the length direction, and the plurality of slings 12 are hung on the hinged block 6, and the driving chain 11 transmission sleeve is arranged on the driving component arranged on the upper end of the boom 4, and the weight of the base 1 and the hoisted pipe pile is borne on the hinged block 6 through the plurality of slings 12, and the driving component is driven by the transmission driving chain 11 to move, thereby realizing the base 1 carrying the pipe pile to transfer.

[0026] The driving assembly includes a sprocket 41, a crown gear 42, a second driving gear 43 and a stepper motor 44; an accommodation cavity is provided at the upper end of the boom 4, and the driving assembly is arranged in the accommodation cavity; a sleeve 45 is provided at the hinged position between the top of the boom 4 and the hinged block 6, and a pin shaft for connecting the boom 4 and the hinged block 6 passes through the middle of the sleeve 45; the sprocket 41 is rotatably sleeved on the outside of the sleeve 45 through a bearing; the driving chain 11 is sleeved on the sprocket 41; the crown gear 42 is coaxially fixed on one side end face of the sprocket 41; the stepper motor 44 is fixedly arranged in the accommodation cavity; the second driving gear 43 is fixed on the driving end of the stepper motor 44; the second driving gear 43 is meshed with the crown gear 42; the operation of the stepper motor 44 drives the second driving gear 43 to mesh and drive the crown gear 42 to rotate, thereby realizing the rotation of the driving sprocket 41 and the displacement of the driving chain 11, thereby realizing the displacement of the driving base 1 carrying the pipe pile.

[0027] The prestressed pipe pile lifting device for high-cold areas also includes two support arms 5; two embedding grooves are arranged on the top surface of the base 1, and the two embedding grooves are symmetrically arranged about the boom 4 in the length direction of the base 1. The two support arms 5 are respectively hinged in the two embedding grooves, and the hinged sides of the two support arms 5 are both located on the side of the embedding groove close to the boom 4. The two support arms 5 are respectively driven by two independently arranged driving motors 2, and the driving motor 2 is embedded in the base 1. The support arms 5 are driven by the driving motor 2 to lift up, so as to stably support the driving chain 11 and the multiple slings 12 to always maintain a stable tension. When the base 1 is rotated to a certain angle, the support arms 5 close to the boom 4 can be retracted into the embedding groove, thereby ensuring that the base 1 can be rotated from a horizontal posture to a vertical posture.

[0028] The swing end of each support arm 5 is rotatably mounted with a roller 51 to reduce the friction between the support arm 5 and the drive chain 11 and the sling 12, thereby increasing the service life of the device.

[0029] The boom 4 and the two supporting arms 5 are hydraulically controlled telescopic rods, and the extension and contraction of the boom 4 and the two supporting arms 5 are precisely regulated by an external hydraulic control system.

[0030] A lifting lug 61 is provided on the top of the hinged block 6 for connection with a lifting and hoisting device.

[0031] A hook 3 is installed at the lower end of the vertical arm of each clamping hanger 2 for safely and smoothly lifting the pipe pile to be transported. The multiple clamping hangers 2 are arranged in an alternating opposite layout, and the tips of the hooks 3 installed on each clamping hanger 2 point to the center of the width direction of the base 1, that is, the multiple clamping hangers 2 are respectively inserted on the base 1 from both sides of the width direction of the base 1, and every two adjacent clamping hangers 2 are respectively located on both sides of the width direction of the base 1. When each driving motor drives the corresponding driving gear 13 to rotate, the multiple clamping hangers 2 can be driven to move towards each other on the base 1 to move together to clamp the pipe pile, or to move away from each other to release to remove the pipe pile.

[0032] Each hook 3 is hinged on the clamping hanger 2, and a hydraulic support rod 31 is arranged on the hinged side of each hook 3. One end of the hydraulic support rod 31 is hinged on the hook 3, and the other end of the hydraulic support rod 31 is hinged on the clamping hanger 2. The hydraulic support rod 31 can be extended or shortened to adjust the angle of the hook 3 on the clamping hanger 2. When the pipe pile is lifted from the placement position, the hydraulic support rod 31 is adjusted to a shortened state to tilt the upper end surface of the hook 3, which is convenient for shoveling the pipe pile. During the lifting process of the pipe pile, the hydraulic support rod 31 is adjusted according to the shape of the pipe pile. The extension of the hydraulic strut 31 is such that when the pipe pile to be hoisted is a square pipe pile, the hydraulic strut 31 is regulated to be sufficiently extended so that the upper end surface of the hook 3 is lifted to a horizontal position, thereby stably supporting the pipe pile. When the pipe pile to be hoisted is a round pipe pile, the hydraulic strut 31 does not need to be fully extended. The hydraulic strut 31 maintains a stable extension, so that the upper end surface of the hook 3 remains inclined, thereby forming an oblique abutment with the round pipe pile, which can increase the contact area between the device and the pipe pile as a whole and improve the stability, reliability and safety of the hoisting.

[0033] Working principle: when it is necessary to lift the pipe pile, the driving motor is pre-regulated to drive the driving gear 13 to rotate, driving the clamping hanger 2 to slide, so that the distance between the clamping hangers 2 on both sides of the base 1 is increased, and they are straddled on both sides of the radial direction of the pipe pile to be lifted, and the hydraulic support rod 31 is regulated to retract, so that the tip of the hook 3 is lowered, and the driving motor is regulated to drive the driving gear 13 to rotate, so that the distance between the clamping hangers 2 on both sides of the transmission base 1 is reduced, and the hook 3 is inserted into the gap between the pipe pile and the placement position to shovel the pipe pile, and the distance between the clamping hangers 2 arranged opposite to each other continues to be reduced to clamp the pipe pile. At this time, the angle of the hook 3 is adjusted according to the shape of the pipe pile, so that multiple hooks 3 can stably support the pipe pile.

[0034] After the pipe pile is hoisted to a specific location, if the pipe pile needs to be erected, the boom 4 is adjusted to be shortened and the two supporting arms 5 are adjusted to be extended to stably support the drive chain 11 and the sling 12 (when the pipe pile is hoisted, the drive chain 11 and the sling 12 are stretched into three shapes by the boom 4, and when the pipe pile is transferred, the drive chain 11 and the sling 12 are stretched into a special shape on the supporting arms 5), and the stepper motor 44 is driven to work, so that the driving gear 2 43 is engaged with the crown gear 42 for operation, and the sprocket 41 is rotated to drive the drive chain 11 to move, and the pulling base 1 is transferred as a whole, thereby realizing the transfer of the pipe pile. When the pipe pile is transferred, the suspension height of the pipe pile is lowered in advance as a whole, so that one end of the pipe pile is grounded to ensure the safety of the process.

[0035] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
