Description

Technical Field

[0001] The invention belongs to the technical field of T-beam support, and in particular relates to a T-beam support device and a support method. Background Art

[0002] T-beam erection is a commonly used bridge structure, characterized by high rigidity and strength. The cross section of the T-beam is T-shaped, with the two sides of the protruding part called flange, and the middle part is called beam rib or web. T-beam erection plays an important role and is widely used in bridge construction. The use of prefabricated T-beams has become the mainstream, and factory production can greatly shorten the on-site construction time.

[0003] At present, there are mainly the following ways to support and fix prefabricated T-beams during storage: one is to support the two sides of the T-beam with logs, steel pipes or sleepers, but this support method has poor stability. According to the overall size of the T-beam and the changes in different cross-sectional sizes, it is necessary to prepare support materials of different lengths, which requires a large amount of support materials; the second is to use pits to fix the bottom of the T-beam, but this method cannot adapt to T-beams with inconsistent length and width, and when placing the T-beam, the lowering position needs to be precisely controlled to prevent damage, so the placement process is more cumbersome; the third is to use vertical pole-type steel pipe support, but this support method is too close to the beam body, the support stability is poor, and the beam body is at risk of overturning. Summary of the invention

[0004] In order to solve the deficiencies in the prior art, the present invention provides a T-beam supporting device and a supporting method, which have good supporting stability for the T-beam, are movable, and have a simple overall structure and are easy to use.

[0005] In order to achieve the purpose of the present invention, the following scheme is proposed: A T-beam supporting device comprises: a chassis and a positioning assembly and a supporting assembly arranged on the chassis; The positioning assembly includes a rotating plate, a positioning hydraulic cylinder and a telescopic device. The rear end of the rotating plate is hinged to the front end of the chassis. The end of the housing of the positioning hydraulic cylinder is hinged to the top of the front end of the rotating plate. One end of the telescopic device is hinged to the front end of the top surface of the chassis, and the other end is hinged to the side wall of the housing of the positioning hydraulic cylinder, which is used to control the pitch of the positioning hydraulic cylinder. The support assembly includes a support rod, a pair of supporting hydraulic cylinders and a pair of telescopic devices. The outer shell end of the supporting hydraulic cylinder is hinged to the rear end of the top surface of the chassis, and the pair of supporting hydraulic cylinders are symmetrically arranged on both sides of the positioning hydraulic cylinder. The telescopic devices are respectively arranged under one of the supporting hydraulic cylinders. One end of the telescopic device is hinged to the chassis, and the other end is hinged to the outer wall of the corresponding supporting hydraulic cylinder for controlling the pitch of the supporting hydraulic cylinder. The two ends of the support rod are respectively vertically connected to the hydraulic rods of the two supporting hydraulic cylinders, and the support rod is located above the positioning hydraulic cylinder.

[0006] The T-beam supporting method is implemented by using the above-mentioned T-beam supporting device, and the method comprises the following steps: S1: Chassis alignment. T-beam support devices are set on both sides of the T-beam. First, the supporting hydraulic cylinder is propped up by the telescopic device, and the hydraulic rod of the supporting hydraulic cylinder is extended so that the supporting rod is parallel to the intersection line between the flange and the beam rib. Then, the positioning hydraulic cylinder is propped up by the telescopic device, and the hydraulic rod of the positioning hydraulic cylinder is extended. The chassis is moved along the length direction of the T-beam so that the end of the hydraulic rod of the positioning hydraulic cylinder is aligned with the reserved hole at the bottom of the flange. S2: Chassis positioning, the positioning hydraulic cylinders on both sides of the T beam extend the hydraulic rods, and insert the front ends of the hydraulic rods into the reserved holes, so that the bottom surface of the front end of the rotating plate abuts against the ground; S3: Support the T-beam. The hydraulic rods of the supporting hydraulic cylinders on both sides of the T-beam continue to extend, and the pitch angle of the supporting hydraulic cylinders is adjusted through the telescopic device so that the supporting rods are pressed against the angle between the flange and the beam rib to provide supporting force to the T-beam.

[0007] The beneficial effects of the present invention are: 1. This solution has good supporting stability and can effectively prevent the T-beam from tilting. This solution is suitable for T-beams of different sizes and different cross-sections of T-beams, and can effectively support the T-beams.

[0008] 2. This solution is an independent support structure, and there is no need to prevent the support device from moving by connecting it to a beam platform or connecting it in pairs, which further improves the convenience of using the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] To make the objectives, technical solutions and advantages of the embodiments of the present invention more clear, the implementation modes of the present invention are described in detail below with reference to the accompanying drawings. However, the embodiments described in the present invention are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Embodiment 1, as Figures 1 to 4 As shown, a T-beam supporting device comprises: a chassis 1 and a positioning component and a supporting component arranged on the chassis 1.

[0021] Specifically, the positioning assembly includes a rotating plate 21, a positioning hydraulic cylinder 22 and a telescopic device 23. The rear end of the rotating plate 21 is hinged to the front end of the chassis 1, and the end of the shell of the positioning hydraulic cylinder 22 is hingedly connected to the front end top of the rotating plate 21. The hinge axes at both ends of the rotating plate 21 are parallel to each other and are parallel to the bottom surface and the front end surface of the chassis 1. One end of the telescopic device 23 is hinged to the front end of the top surface of the chassis 1, and the other end is hinged to the side wall of the shell of the positioning hydraulic cylinder 22, which is used to control the pitch of the positioning hydraulic cylinder 22. Specifically, the shell end of the telescopic device 23 can be hinged to the chassis 1, and the telescopic rod of the telescopic device 23 can be hinged to the positioning hydraulic cylinder 22.

[0022] Specifically, the support assembly includes a support rod 31, a pair of support hydraulic cylinders 32 and a pair of telescopic devices 33. The outer shell end of the support hydraulic cylinder 32 is hinged to the rear end of the top surface of the chassis 1, and the pair of support hydraulic cylinders 32 are symmetrically arranged on both sides of the positioning hydraulic cylinder 22. The telescopic devices 33 are respectively arranged under one of the support hydraulic cylinders 32. One end of the telescopic device 33 is hinged to the chassis 1, and the other end is hinged to the outer wall of the corresponding support hydraulic cylinder 32, which is used to control the pitch of the support hydraulic cylinder 32. Specifically, the outer shell end of the telescopic device 33 can be hinged to the chassis 1, and the telescopic rod of the telescopic device 33 can be hinged to the support hydraulic cylinder 32; the two ends of the support rod 31 are respectively vertically connected to the hydraulic rods of the two support hydraulic cylinders 32, and the support rod 31 is located above the positioning hydraulic cylinder 22.

[0023] Specifically, Figures 1 to 3As shown, when the T-beam support device is in the folded state, the telescopic device 23 is folded, the positioning hydraulic cylinder 22 is supported flat on the chassis 1, and the hydraulic rod of the positioning hydraulic cylinder 22 is folded, and the rotating plate 21 is higher than the bottom surface of the chassis 1, so as to facilitate the transfer of the T-beam support device through the chassis 1; the telescopic device 33 is folded, the supporting hydraulic cylinder 32 is supported flat on the chassis 1, and the hydraulic rod of the supporting hydraulic cylinder 32 is folded, and the heights of the supporting hydraulic cylinder 32 and the supporting rod 31 are both higher than the positioning hydraulic cylinder 22; when the T-beam support device is folded, the overall structure is compact, which is convenient for placement and transfer.

[0024] Specifically, Figures 4 to 8 As shown, when the T-beam supporting device is working, the bottom surface of the chassis 1 is in contact with the ground, the telescopic device 23 is extended, the hydraulic rod of the positioning hydraulic cylinder 22 is extended, and is tilted toward the upper rear of the chassis 1, and the end of the hydraulic rod of the positioning hydraulic cylinder 22 is inserted into the reserved hole at the bottom of the T-beam flange, and the front bottom surface of the rotating plate 21 is in contact with the ground; the telescopic device 33 is extended, the hydraulic rod of the supporting hydraulic cylinder 32 is extended, and is tilted toward the upper front of the chassis 1, and the supporting rod 31 is in contact with the angle formed by the flange of the T-beam and the beam rib.

[0025] When supporting a T-beam, it is usually necessary to set the above-mentioned T-beam support device on both sides of the T-beam to prevent the T-beam from tipping over toward the other side where the T-beam support device is set. The T-beam support devices set on both sides of the T-beam in this solution are independent individuals and do not need to be connected and fixed to each other. In order to prevent the support device from sliding to the outside of the T-beam during operation, some existing support devices usually need to connect the support devices on both sides of the T-beam through connecting rods or pull ropes to ensure that the distance between the support device and the T-beam remains unchanged when supporting the T-beam.

[0026] like Figures 3 to 8As shown, the supporting principle of this scheme is as follows: the bottom surface of the chassis 1 is supported by the ground, providing support force and friction force to the T-beam support device. The support rod 31 abuts against the angle formed by the flange of the T-beam and the beam rib, and uses the support hydraulic cylinder 32 to provide the T-beam with a support force toward the upper middle of the T-beam to prevent the T-beam from tipping over to the side where the T-beam support device is set. However, at the same time, the support force generated by the support hydraulic cylinder 32 will generate a directional force on the chassis 1 while supporting the T-beam, causing the chassis 1 to slide in the direction away from the T-beam, resulting in support failure; therefore, the hydraulic rod of the positioning hydraulic cylinder 22 is used to cooperate with the reserved hole at the bottom of the flange, and the front end bottom surface of the rotating plate 21 for installing the positioning hydraulic cylinder 22 abuts against the ground, so that the positioning hydraulic cylinder 22 forms a top rod structure that is obliquely supported between the bottom of the flange and the ground, and the inclination direction of the positioning hydraulic cylinder 22 is opposite to the inclination direction of the support hydraulic cylinder 32, and the lower ends of the positioning hydraulic cylinder 22 and the support hydraulic cylinder 32 are directly or indirectly installed on the chassis 1, so that the lower ends of the two The distance between them is a fixed value, and the upper ends of the hydraulic rods of the positioning hydraulic cylinder 22 and the supporting hydraulic cylinder 32 are limited by the reserved holes and the angle formed by the flange and the beam rib, so that the distance between the upper ends of the hydraulic rods of the positioning hydraulic cylinder 22 and the supporting hydraulic cylinder 32 is also a fixed value; in this way, the positioning hydraulic cylinder 22 and the supporting hydraulic cylinder 32 form an X-shaped cross-support structure, which not only prevents the chassis 1 from moving in the direction of the original T-beam when the supporting hydraulic cylinder 32 is working, but also further improves the support stability of the T-beam; because the rotating plate 21 is hinged on the chassis 1, a height difference is allowed between the ground it contacts and the ground the chassis 1 contacts, so as to adapt to various uneven ground uses. The support rod 31 abuts against the T-beam in a linear contact manner, which can effectively prevent the T-beam support device from tilting to the left and right directions and improve the stability of the T-beam support.

[0027] Preferably, the telescopic component 23 and the telescopic device 33 are both hydraulic cylinder structures.

[0028] Preferably, the telescopic device 23, the telescopic device 33, the positioning hydraulic cylinder 22 and the supporting hydraulic cylinder 32 are all provided with hydraulic sensors for real-time monitoring of the pressure status of each T beam, thereby assisting in determining the supporting status of the T beam; specifically, the signal of the hydraulic sensor can be connected to the controller or alarm system, and when the pressure value exceeds a predetermined limit, the staff can be prompted to take measures through an alarm to prevent the T beam from tipping over.

[0029] Preferably, a hydraulic oil tank is provided inside the chassis 1, and a hydraulic pump and a hydraulic control system are provided on the top to facilitate overall transfer and use.

[0030] Preferably, Figures 1 to 4As shown, rollers 11 are provided around the chassis 1, and the height position of the rollers 11 relative to the chassis 1 is adjustable. The purpose of providing the rollers 11 is to facilitate the transfer of the T-beam support device, and when in use, the rollers 11 can be raised and supported by the bottom surface of the chassis 1 to avoid the problem of support failure caused by insufficient support strength of the rollers 11. Specifically, the rollers 11 can be installed around the chassis 1 by screws, so that the height of the rollers 11 can be conveniently controlled by rotating the screws. As another preferred solution, the lifting and lowering of the rollers 11 can be automatically adjusted by a telescopic cylinder or a telescopic motor; and the movement of the chassis 1 can be controlled by a remote control device.

[0031] Preferably, Figure 4 As shown, a plurality of support plates 12 are provided on the top of the chassis 1, which are respectively used to support the positioning hydraulic cylinder 22 and the supporting hydraulic cylinder 32. When the supporting positioning hydraulic cylinder 22 and the supporting hydraulic cylinder 32 are supported on the corresponding support plates 12, the supporting positioning hydraulic cylinder 22 and the supporting hydraulic cylinder 32 are both in a lying state, and the front end bottom surface of the rotating plate 21 is higher than the bottom surface of the chassis 1, so as to facilitate the overall transfer of the T-beam support device.

[0032] Preferably, Figure 1 , Figure 3 and Figure 4 As shown, the bottom surface of the front end of the rotating plate 21 is provided with a wear-resistant plate 211 with an arc structure, the arc surface of the wear-resistant plate 211 faces downward, and the axis of the arc surface is consistent with the width direction of the chassis 1. The wear-resistant plate 211 contacts the ground so that the rotating plate 21 can adapt to the ground at different heights to increase the adaptability of the device.

[0033] Preferably, Figures 1 to 3 As shown, the length of the positioning hydraulic cylinder 22 and the supporting hydraulic cylinder 32 after being folded is smaller than the distance between the front end of the rotating plate 21 and the rear end of the chassis 1, so as to improve the compactness of the T-beam supporting device.

[0034] Embodiment 2, a T-beam supporting method, implemented by using the T-beam supporting device described in Embodiment 1, the method comprises the following steps: S1: Chassis 1 is aligned, and T-beam supporting devices are set on both sides of the T-beam. First, the supporting hydraulic cylinder 32 is propped up by the telescopic device 33, and the hydraulic rod of the supporting hydraulic cylinder 32 is extended so that the supporting rod 31 is parallel to the intersection line between the flange and the beam rib. The purpose of this step is to make room for the positioning hydraulic cylinder 22 to move and at the same time determine the angle between the chassis 1 and the T-beam so that the front and rear end connection line of the chassis 1 is perpendicular to the T-beam. Then, the positioning hydraulic cylinder 22 is propped up by the telescopic device 23, and the hydraulic rod of the positioning hydraulic cylinder 22 is extended. The chassis 1 is moved along the length direction of the T-beam so that the end of the hydraulic rod of the positioning hydraulic cylinder 22 is aligned with the reserved hole at the bottom of the flange.

[0035] S2: The chassis 1 is positioned. The positioning hydraulic cylinders 22 on both sides of the T-beam extend the hydraulic rods and insert the front ends of the hydraulic rods into the reserved holes. The bottom surface of the front end of the rotating plate 21 abuts against the ground. During this process, the pressure generated by the positioning hydraulic cylinders 22 fixes the rotating plate 21 to the ground to prevent the chassis 1 from moving. Because the rotating plate 21 is hingedly connected to the chassis 1, the chassis 1 will not move with the rotating plate 21 during this process.

[0036] S3: Support the T-beam. The hydraulic rods of the supporting hydraulic cylinders 32 on both sides of the T-beam continue to extend, and the pitch angle of the supporting hydraulic cylinders 32 is adjusted through the telescopic device 33, so that the supporting rod 31 is pressed against the angle between the flange and the beam rib to provide supporting force to the T-beam.

[0037] The above description is only a preferred embodiment of the present invention, and does not represent the only or limit the present invention. Those skilled in the art should understand that various changes or equivalent substitutions made to the present invention without departing from the scope of the present invention are within the scope of protection of the present invention.
