Description

Technical Field

[0001] The utility model relates to the technical field of box girder end maintenance, in particular to a prefabricated box girder end maintenance tooling installation and disassembly device. Background Art

[0002] With the rapid development of high-speed railway construction, the quality requirements of prestressed concrete simply supported box girders have gradually increased, and the maintenance requirements and maintenance effects of box girders have gradually received attention. Inadequate maintenance may directly affect the strength and durability of the girder body. During construction, box girder maintenance must be all-round and without dead angles, and the maintenance of box girder ends has always been a key and difficult point in box girder maintenance.

[0003] Traditional prefabricated box girder end curing supports are typically hoisted using a lifting device, with manual intervention using a hook to move the support to the box girder end for installation. Existing hoisting devices can only lift vertically, but in practice, the support also needs to be moved horizontally. This is currently a manual operation, resulting in low overall efficiency.

DETAILED DESCRIPTION

[0032] The following describes the embodiments of the present invention through specific examples. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different perspectives and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features within these embodiments may be combined with one another, unless they conflict.

[0033] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention. Therefore, the drawings only show components related to the present invention and are not drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated. Example

[0034] like Figures 1 to 6 As shown, a prefabricated box girder end maintenance tooling installation and disassembly device includes a walking mechanism 1. Specifically, the walking mechanism 1 includes at least a plate body and walking wheels located at the bottom of the plate body, and can be a common planar walking mechanism on the market.

[0035] A lifting mechanism 2 is fixedly arranged on the walking mechanism 1; in this solution, the lifting mechanism 2 includes a base frame 21, and two parallel main beams 22 are vertically arranged on the upper surface of the base frame 21; an inner frame 23 is embedded on the inner side of the main beam 22; a walking bracket 24 is slidably arranged on the inner frame 23 along the vertical direction, and the receiving frame 3 is fixedly installed on one side of the walking bracket 24; in this solution, in order to achieve stable movement of the walking bracket 24, the vertically horizontal frame beams in the inner frame 23 can be set as slide rails; the walking bracket 24 is connected to the vertically horizontal frame beams in the inner frame 23 by a roller group. Specifically, a number of rollers are set on the vertical beam side of the walking bracket 24.

[0036] To control the up and down movement of the traveling frame 24, a drive mechanism is provided. The drive mechanism includes a first pulley 201 fixed to the top lower surface of the inner frame 23, a second pulley 202 fixed below the first pulley 201 via a support arm 25, a third pulley 203 fixed to the bottom upper surface of the inner frame 23, and a fixing ring 204 fixed to the receiving frame 3. A winch 20 is fixed to the base frame 21. The traction line of the winch 20 passes through the first pulley 201, the third pulley 203, and the second pulley 202 in sequence and is fixedly connected to the fixing ring 204. The winch 20 retracts or releases the wire harness to achieve movement of the receiving frame 3.

[0037] A receiving frame 3 is vertically slidably mounted on the lifting mechanism 2. The receiving frame 3 is composed of a vertical frame 31 and a horizontal frame 32. The vertical frame 31 is fixedly connected to the receiving frame 3. The guide rail assembly 4 is mounted on the bottom of the horizontal frame 32. Specifically, two parallel mounting beams 41 are longitudinally welded and fixed to the horizontal frame 32.

[0038] Then, an I-beam 42 is welded horizontally to the bottom of the two mounting beams 41 at the same time. Due to the structure of the I-beam 42 , the two groove surfaces of the I-beam 42 can be set as guide rail grooves. The hanging assembly 5 is embedded and slidable in the guide rail grooves.

[0039] Furthermore, to increase the travel length of the I-beam 42, an extended I-beam 43 is hingedly mounted on the outer mounting beam 41 via a connector 44. After being flipped, the extended I-beam 43 forms a travel guide with the I-beam 42 for the suspension assembly 5. A limiter 45 is also provided on the outer mounting beam 41. A notch 4301 is provided on the upper surface of the extended I-beam 43. After the extended I-beam 43 is flipped, the notch 4301 engages with the limiter 45. This flipped and spliced assembly allows for a longer travel length for the suspension assembly 5.

[0040] In this solution, the lifting assembly 5 includes a U-shaped groove 51, and a plurality of groups of walking rollers 52 are arranged in an array inside the U-shaped groove 51. A motor 53 is arranged outside the U-shaped groove 51, and the output end of the motor 53 is connected to one of the walking rollers 52 to control the movement of the U-shaped groove 51 on the I-beam 42 and the extended I-beam 43; a hook 55 is provided at the bottom of the U-shaped groove 51 through a hinge seat 54.

[0041] By adding a guide rail assembly to the lifting mechanism, the lifting device can be moved horizontally, which improves the installation efficiency of the maintenance bracket. At the same time, the use of an extended I-beam that can be folded can increase the horizontal movement stroke without changing the size of the device space, thereby increasing the lifting movement stroke and effectively reducing the difficulty of lifting.

[0042] The above-described embodiments merely represent specific implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
