Description

Technical Field

[0001] The invention relates to the field of construction pile driving preparation auxiliary devices, in particular to a steel pile erecting device at a construction site. Background Art

[0002] During construction, because the ground has to bear great pressure if the building is to be built on the ground, it is necessary to ensure that the ground has enough strength to resist the pressure. This is often difficult to do, so the ground that supports the building must be reinforced or the way the ground bears the pressure must be improved. So people think of driving piles into the foundation, so that most of the weight of the building can be transferred to a position deep below the ground through the piles, because the foundation at this position has a much greater bearing capacity than the ground.

[0003] There are usually two types of foundation piles involved in construction. One is cement piles, which are usually formed by pouring piles after digging a deep pit with a pile driver. When a building needs to bear a large weight, steel piles are often needed. Steel piles cannot be poured into the ground like cement piles. During operation, the steel piles need to be erected first and then driven into the ground.

[0004] In the prior art, the main method of erecting steel piles is to use a mode of manual and mechanical lifting. During the lifting process, due to the lack of support points, the steel piles are prone to shaking, which is a great hidden danger of safety accidents. Therefore, how to stably erect steel piles to avoid safety hazards has become an urgent problem to be solved in the field of construction pile preparation auxiliary devices. Summary of the invention

[0005] The purpose of the present invention is to overcome the deficiency of the prior art that insufficient support is provided when erecting steel piles, causing the steel piles to shake easily and thus creating a great safety hazard. A device for erecting steel piles at a construction site is provided, which provides support for one side of the steel pile when hoisting the steel pile to enhance its stability and achieve the purpose of effectively avoiding safety hazards.

[0006] The purpose of the present invention is mainly achieved through the following technical solutions:

[0007] The device for erecting steel piles at construction sites comprises a guide platform capable of guiding the placement of steel piles, a plurality of gripping legs being evenly fixed below the guide platform, two telescopic supports being arranged on a side surface of the guide platform perpendicular to the axis of the steel pile, the two telescopic supports being symmetrically distributed on both sides of the steel pile, a connecting rod being arranged on the telescopic support, one end of the connecting rod being fixed to the telescopic support, and the other end of the connecting rod being provided with a support bracket, the support bracket being hinged to the connecting rod, a wire take-up device being arranged on both sides of the guide platform which avoid the telescopic support and are opposite to each other, the wire take-up device being fixed to the guide platform, a pulling rope being arranged inside the wire take-up device, one end of the pulling rope being able to freely retract inside the wire take-up device, and the other end of the pulling rope being provided with a fixing ring sleeve which can be sleeved on the steel pile, the fixing ring sleeve being fixed to the pulling rope, a support frame being arranged below the fixing ring sleeve, and the pulling rope being placed on the support frame.

[0008] At present, when it is necessary to use the form of driving steel piles into the ground for construction in building construction, the steel piles need to be erected first. Since steel piles are generally long and heavy, the process of erecting steel piles becomes very dangerous. The erection process needs to be stable and provide sufficient support. The existing technology usually adopts a hoisting method to erect steel piles. However, in the process of erecting steel piles, there is no support, which is a huge safety hazard for the construction party. Therefore, it is particularly important to provide sufficient support for the steel piles during the erection process so that the steel piles can be erected stably. Based on the work of erecting steel piles, the present invention first adopts a guide platform to ensure that the steel piles are in the correct direction when hoisted and will not shake. The gripping feet enable the force received by the guide platform to be effectively transmitted to the ground. The invention can effectively prevent the guide platform from tipping over and improve the gripping ability of the guide platform. The wire take-up device can effectively retract the pulling rope, so that the fixed ring sleeve can assist in providing pulling force for erecting the steel pile, and the telescopic support can effectively support the steel pile through the connecting rod and the support bracket, while also preventing the steel pile from shaking during the lifting process. The present invention effectively assists the process of lifting the steel pile under the support of the support frame through the fixed ring sleeve and the pulling rope, and effectively controls the movement direction of the steel pile during erection through the guide platform, the telescopic support and the support bracket, so that the steel pile can be erected more stably during the erection process, effectively avoiding safety hazards. The present invention provides support for one side of the steel pile when lifting the steel pile to enhance its stability, thereby achieving the purpose of effectively avoiding safety hazards.

[0009] Furthermore, the guide platform includes a platform shell, and a guide groove is opened on the upper surface of the platform shell. The guide groove runs through the side surface of the telescopic support and the opposite side surface thereof. A plurality of transverse rollers are evenly arranged on the groove surface in the guide groove, and a plurality of vertical rollers are evenly arranged on the two side walls of the guide groove. The transverse rollers and vertical rollers can rotate freely. The arrangement of the transverse rollers and vertical rollers in the present invention makes it easier for the steel pile to move in the guide groove, avoiding the hindrance of the movement of the steel pile caused by friction resistance. At the same time, due to the arrangement of the guide groove, the range of movement of the steel pile is limited, so that the guide platform can effectively guide the steel pile to avoid its shaking during the erection start.

[0010] Furthermore, the telescopic support includes a pushing base, which is located in the guide platform. A fixing rod is provided on the side of the pushing base, one end of the fixing rod is fixed to the pushing base, and the other end thereof is fixed to the inner wall of the guide platform. A hydraulic pushing rod is provided on the pushing base, one end of the hydraulic pushing rod is fixed to the pushing base, and the other end thereof extends out of the guide platform. An L-shaped rod is provided at the end of the hydraulic pushing rod close to the outside of the guide platform, one end of the L-shaped rod is fixed to the hydraulic pushing rod, and the other end thereof is provided with a fixing sleeve. The end of the L-shaped rod is sleeved in the fixing sleeve, and a support rod and a balancing rod are symmetrically provided on the fixing sleeve to avoid the position of the L-shaped rod. The support rod is hinged to the fixing sleeve, and the balancing rod is fixed to the fixing sleeve. The telescopic support of the present invention is based on a pushing base, and the support bracket and the connecting rod are effectively supported by the pushing of a hydraulic pushing rod, and can follow the erection of the steel pile and gradually extend to continue to provide support. The pushing base is supported by the fixing rod and effectively bears the weight brought by the steel pile. The L-shaped rod enables the fixing sleeve to be removed from the telescopic support, and the fixing sleeve is taken and placed on the L-shaped rod to avoid the support bracket and the steel pile from not fitting. The balance rod and the support rod are fixed on the fixing sleeve, and the symmetrical arrangement of the support rod and the balance rod avoids the risk of deformation caused by weight imbalance.

[0011] Furthermore, the support bracket includes a first arc support plate and a second arc support plate, the first arc support plate and the second arc support plate are respectively fixed on the two telescopic supports, and the first arc support plate and the second arc support plate can be spliced ​​and fixed to form a complete semicircular arc plate. Through the support of the two arc support plates, the steel pile is effectively supported and can be prevented from shaking during the erection process.

[0012] Furthermore, the first arc-shaped pallet includes a first pallet shell, which is a hollow quarter-arc plate, and a first motor fixed in the first pallet shell is provided at one end of the first pallet shell, and a rotating screw is provided at the output end of the first motor, and the rotating screw extends out of the first pallet shell, and a first pallet support filling capable of completely filling the first pallet shell is provided in the first pallet shell; the second arc-shaped pallet includes a second pallet shell, which can be spliced ​​with the first pallet shell to form a complete semi-arc plate, and a built-in nut is fixed at one end of the second pallet shell, and the built-in nut matches the rotating screw, and a second pallet support filling capable of completely filling the second pallet shell is provided in the second pallet shell. The first motor on the first support plate shell in the present invention can effectively drive the rotating screw to rotate, and the rotating screw will enter the built-in nut on the second support plate shell when it rotates. Through the cooperation of the built-in nut and the rotating screw, the first arc-shaped support plate and the second arc-shaped support plate are effectively locked to prevent them from dispersing during the support process of the erection of the steel piles and causing a lack of supporting force. The first support plate support filling and the second support plate support filling are made of rigid materials, which can not only effectively support and avoid deformation, but also avoid the risk of breakage under the protection of the shell.

[0013] Furthermore, the support frame includes a triangular support, a top support platform is fixed above the triangular support, a pulley is fixed above the top support platform, the number of pulleys matches the number of pull ropes, and the pull rope is connected to the fixed ring sleeve through the pulley. The present invention uses a pulley to support the pull rope, and the pulley can more effectively support the force of the pull rope, and the triangular support has strong stability, which can also ensure the stability of the support. The top support platform can effectively transmit the force received downward to avoid deformation at the pulley.

[0014] Furthermore, the fixing ring comprises a first half ring and a second half ring, the first half ring and the second half ring are respectively fixed on the pulling rope outside the two wire take-ups, and the first half ring and the second half ring can be spliced ​​and fixed into a complete circular ring. By locking the two half rings, the pulling rope can evenly and effectively apply tension to the steel pile in the circumferential direction.

[0015] Furthermore, the first half ring includes a first ring sleeve shell, which is a hollow semicircular ring plate, and a second motor fixed in the first ring sleeve shell is provided at both end portions of the first ring sleeve shell, and a locking screw is provided at the output end of the second motor, and the locking screw extends out of the first ring sleeve shell, and a first ring sleeve support filling capable of completely filling the first ring sleeve shell is provided in the first ring sleeve shell; the second half ring includes a second ring sleeve shell, and the second ring sleeve shell can be spliced ​​with the first ring sleeve shell to form a complete circular ring plate, and locking nuts are fixed at both end portions of the second ring sleeve shell, and the locking nuts match the locking screws, and a second ring sleeve support filling capable of completely filling the second ring sleeve shell is provided in the second ring sleeve shell. The second motor on the first ring sleeve shell in the present invention can effectively drive the locking screw to rotate, and the locking screw will rotate and enter the locking nut on the second ring sleeve shell. Through the cooperation of the locking nut and the locking screw, the first half ring and the second half ring are effectively locked, and the steel pile is wrapped from the circumferential direction to avoid uneven force. The steel pile can also be effectively pulled. The filling material used for the first ring sleeve support filling and the second ring sleeve support filling is metal material, which avoids unstable movement of the steel pile due to deformation of the fixed ring sleeve during the pulling process.

[0016] In summary, the present invention has the following beneficial effects compared with the prior art:

[0017] (1) The present invention effectively controls the movement direction of the steel pile during erection through the guide platform, telescopic support and support bracket, so that the steel pile can be erected more stably during the erection process, effectively avoiding safety hazards.
