Description

Technical Field

[0001] The utility model relates to the technical field of bridge engineering construction, in particular to a telescopic support leg of assembled beam-column erection equipment. Background Art

[0002] Prefabricated piers and caps refer to a construction method in which bridge components are prefabricated in the factory and then transported to the construction site for assembly. Compared with traditional on-site casting, this method has the advantages of short construction period, controllable quality, and convenient construction. The outrigger design of prefabricated piers and caps is an important part of bridge construction, which is related to the stability of the structure and the safety of construction. In prefabricated bridge projects, outriggers are usually used to support piers and caps to ensure stability during the construction process, while also considering the structural bearing capacity after the construction is completed.

[0003] However, there is no mature special equipment for erecting heavy-weight prefabricated piers and cap beams. In addition, the height difference of piers is large and there are many types. The height adjustment of the outriggers during construction is large and difficult. At present, the main method for adjusting the height of the outriggers is to add brackets and pads. This method is difficult to adjust the height, time-consuming and labor-intensive.

[0004] Therefore, in view of the above problems, a prefabricated beam-column erection equipment with telescopic legs is proposed to solve the above problems. Utility Model Content

[0005] Aiming at the deficiencies of the prior art, the utility model develops a telescopic support leg of assembled beam-column erection equipment, and the utility model can quickly adjust the height of the main beam on the support leg.

[0006] The technical solution to the technical problem solved by the utility model is: an assembled beam-column erection equipment with telescopic legs, comprising a main beam and legs, the legs comprising symmetrically vertically arranged support rods, the legs horizontally clamped with the main beam, the main beam comprising an upper beam and a lower beam, the upper beam and the lower beam being connected by a plurality of reinforcing rods, the main beam being provided with a driving structure connected to the legs, a plurality of locking structures being symmetrically arranged between the main beam and the legs, and an adjustment structure being arranged at the lower end of the legs.

[0007] The main beam is driven up and down by the driving structure. After reaching the corresponding height, the locking structure is activated to lock the position of the main beam. At the same time, fine-tuning is performed through the adjustment structure at the lower end of the support leg to make the height of the main beam more accurate.

[0008] Preferably, the driving structure includes a mounting platform, a lifting hydraulic cylinder, a mounting seat and a connecting platform. The mounting platform is arranged at the lower end of the upper beam, a lifting hydraulic cylinder is arranged under the mounting platform, a mounting seat is arranged at the lower end of the lifting hydraulic cylinder, and the mounting seat is located on the connecting platform.

[0009] Preferably, the driving structure also includes mounting bolts, a U-shaped plate and a locking structure. The U-shaped plates are symmetrically arranged at both ends of the connecting platform. The U-shaped plates are connected to the connecting platform by mounting bolts. The U-shaped plates are slidably connected to the legs, and the U-shaped plates are connected to the legs by a locking structure.

[0010] When the main beam needs to be lifted, the locking structure on the connecting platform is locked first, and at the same time, the lifting hydraulic cylinder is started to drive the main beam to move upward. After the main beam is lifted to a predetermined height, the locking structure between the main beam and the support leg is locked, and the locking structure on the connecting platform is unlocked. At the same time, the lifting hydraulic cylinder retreats. After retreating, the locking structure on the connecting platform is locked. When the main beam needs to be lowered, the locking structure on the connecting platform is unlocked, and the lifting hydraulic cylinder drives the connecting platform to move downward. After reaching the predetermined position, the locking structure on the connecting platform is locked, and the locking structure between the main beam and the support leg is unlocked. The lifting hydraulic cylinder drives the main beam to move downward. After the movement is completed, the locking structure between the main beam and the support leg is locked.

[0011] Preferably, the locking structure includes a displacement sensor, a limit block, a locking rod, a connecting plate, a fixing bolt and an electromagnetic sleeve. The electromagnetic sleeve is slidably connected to the locking rod. A connecting plate is arranged at one end of the electromagnetic sleeve that is slidably connected to the locking rod. The displacement sensor is arranged on the electromagnetic sleeve. The connecting plate is symmetrically arranged above and below the locking rod. The limit block and the connecting plate are connected by fixing bolts.

[0012] The locking mechanism is connected to the main beam and the connecting platform through a limit block. When the locking mechanism needs to be unlocked, the electromagnet in the electromagnetic sleeve is started. Under the action of the electromagnet, the locking rod retracts into the electromagnetic sleeve, thereby unlocking the locking structure. The displacement sensor on the electromagnetic sleeve detects the formation of the locking rod to determine whether it is completely unlocked or locked. The displacement sensor uses the XM-D51 model.

[0013] Preferably, the locking structure also includes a limiting ring, a reset spring and a positioning hole. A plurality of positioning holes are evenly arranged on the support rod. The locking rod is inserted into the positioning hole. A limiting ring is arranged on the locking rod. A reset spring is sleeved on the locking rod. One end of the reset spring is connected to the limiting ring, and the other end of the reset spring is connected to the electromagnetic sleeve.

[0014] When the locking structure needs to be locked, the electromagnet in the electromagnetic sleeve is powered off, the locking rod pops out under the action of the reset spring, and the popped-out locking rod penetrates into the positioning hole of the support rod to achieve locking.

[0015] Preferably, the adjustment structure includes a supporting hydraulic cylinder, a connecting rod and an extension rod. An extension rod is arranged at the lower end of one adjacent support rod and a connecting rod is arranged at the lower end of the other adjacent support rod. The extension rod is arranged vertically, and the connecting rod is arranged obliquely and connected to the extension rod. A supporting hydraulic cylinder is arranged at the lower end of the extension rod.

[0016] When the height of the main beam needs to be precisely adjusted, the height can be adjusted through the supporting hydraulic cylinder at the lower end of the extension rod, making the height adjustment of the main beam more precise.

[0017] The effects provided in the utility model content are only the effects of the embodiments, not all the effects of the utility model. The above technical solution has the following advantages or beneficial effects:

[0018] The locking structure of the equipment integrates the locking rod function, which enables the locking rod to be automatically inserted and disengaged, reducing human intervention; the locking rod insertion action relies on the spring force, and the locking rod automatically rebounds after the electromagnet is powered off, which is safe and efficient;

[0019] When the height of the main beam needs to be precisely adjusted, the height can be adjusted through the supporting hydraulic cylinder at the lower end of the extension rod, making the height adjustment of the main beam more precise. By coordinating these two methods, the rear outrigger height can be infinitely adjusted over a wide range, thereby improving the adaptability to piers with large height differences.

Multiple locking structures are symmetrically arranged between the main beam 1 and the legs 2. An adjustment structure is arranged at the lower end of the legs 2. The main beam 1 is driven by the driving structure to move up and down. After reaching the corresponding height, the locking structure is activated to lock the position of the main beam 1. At the same time, the adjustment structure at the lower end of the legs 2 is used to make fine adjustments, so that the height of the main beam 1 is more accurate.

[0028] The driving structure includes a mounting platform 7, a lifting hydraulic cylinder 8, a mounting seat 9 and a connecting platform 10. The mounting platform 7 is arranged at the lower end of the upper beam 4, the lifting hydraulic cylinder 8 is arranged under the mounting platform 7, the mounting seat 9 is arranged at the lower end of the lifting hydraulic cylinder 8, and the mounting seat 9 is located on the connecting platform 10.

[0029] The driving structure also includes mounting bolts 11, U-shaped plates 12 and locking structures. U-shaped plates 12 are symmetrically arranged at both ends of the connecting platform 10. The U-shaped plates 12 are connected to the connecting platform 10 by mounting bolts 11. The U-shaped plates 12 are slidably connected to the legs 2. The U-shaped plates 12 are connected to the legs 2 by locking structures. When the main beam 1 needs to be lifted, the locking structure on the connecting platform 10 is first locked, and at the same time, the lifting hydraulic cylinder 8 is started to drive the main beam 1 to move upward. After the main beam 1 is lifted to a predetermined height, the locking structure between the main beam 1 and the legs 2 is locked, and the locking structure on the connecting platform 10 is unlocked. At the same time, the lifting hydraulic cylinder 8 retreats. After retreating, the locking structure on the connecting platform 10 is locked.

The limit block 14 and the connecting plate 16 are connected by a fixing bolt 17. The locking mechanism is connected to the main beam 1 and the connecting platform 10 through the limit block 14. When the locking mechanism needs to be unlocked, the electromagnet in the electromagnetic sleeve 18 is started. Under the action of the electromagnet, the locking rod 15 retracts into the electromagnetic sleeve, thereby unlocking the locking structure. The displacement sensor 13 on the electromagnetic sleeve 18 detects the formation of the locking rod 15 to determine whether it is completely unlocked or locked. The displacement sensor 13 uses the XM-D51 model.

[0031] The locking structure also includes a limiting ring 19, a reset spring 20 and a positioning hole 21. A plurality of positioning holes 21 are evenly arranged on the support rod 3.

One end of the reset spring 20 is connected to the limiting ring 19, and the other end of the reset spring 20 is connected to the electromagnetic sleeve 18. When the locking structure needs to be locked, the electromagnet in the electromagnetic sleeve 18 is powered off, and the locking rod 15 pops out under the action of the reset spring 20.

[0033] Working principle: when the main beam 1 needs to be lifted, the locking structure on the connecting platform 10 is locked first, and the locking structures on the main beam 1 and the outrigger 2 are unlocked. At the same time, the lifting hydraulic cylinder 8 is started to drive the main beam 1 to move upward. After the main beam 1 is lifted to a predetermined height, the locking structure between the main beam 1 and the outrigger 2 is locked first, and the locking structure on the connecting platform 10 is unlocked. At the same time, the lifting hydraulic cylinder 8 retreats. After retreating, the locking structure on the connecting platform 10 is locked.
