Description

Technical Field

[0001] The present invention relates to bridge inspection equipment, in particular to a bridge beam bottom inspection device. Background Art

[0002] As the rail transit network in and around my country's cities becomes increasingly dense, railways are also developing in a three-dimensional direction. In this process, it is inevitable that new bridges will overlap with existing lines. Most of the time, new bridges cross existing lines. To ensure the safety of train operation, the clearance of existing lines is restricted, and the lower chord inspection vehicle must not intrude into the train limit. However, the drive support rods on the top of the structural bracket of an ordinary inspection vehicle are generally arranged in a straight line above the truss, and the drive device is installed above the support rods, resulting in the drive device and the drive support rods encroaching on the clearance. In addition, the ordinary bracket is an integral welded structure. The bracket needs to be finally welded to the truss structure and transported together with the truss structure. The bracket of the large-width truss structure is wider and needs to be separated from the truss structure during transportation and then assembled at the bridge site. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a bridge beam bottom inspection device with a compact structure and less clearance height encroachment.

The brackets are arranged below the running tracks. The brackets include bottom support members and side support members. The bottom support members and side support members form an accommodating space. The truss structure is arranged in the accommodating space. The bracket is provided with a driving device for driving the bracket to move along the running tracks.

[0006] As a further improvement of the above technical solution:

[0007] The bracket also includes a top support assembly that is detachably connected to the side supports.

[0008] The side support member is provided with a fixed connection seat, and the top support assembly is detachably connected to the fixed connection seat.

[0009] The top support assembly includes a top rod and a reinforcement core, and the reinforcement core is fixedly connected inside the top rod.

[0010] The push rod is a square tube, an I-beam or a channel steel.

[0011] The truss structure includes a plurality of sub-trusses, and the sub-trusses are connected into a whole.

[0012] There are two groups of top support components, the driving track is arranged between the two groups of top support components, and the bottom surface of the driving track is located between the top surface of the top support component and the top surface of the truss structure.

[0013] The bracket is provided with mounting frames on two opposite sides along the length direction of the traveling track, and the driving device is arranged on the mounting frames.

[0014] The mounting frame is also provided with a locking device for fixing the position of the bracket.

[0015] The locking device is a rail clamp.

[0016] Compared with the prior art, the advantages of the present invention are: a bridge beam bottom inspection device disclosed in the present invention includes a bracket, which is provided with a bottom support member and a side support member to form a truss structure accommodation space, so that inspectors can walk on the truss structure to reduce the truss structure from encroaching on the clearance; the driving device is directly arranged on the bracket, which solves the problem of the driving support rod in ordinary inspection vehicles encroaching on the clearance, and the structure is compact and stable.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Figures 1 to 5An embodiment of the bridge beam bottom inspection device of the present invention is shown. The bridge beam bottom inspection device of this embodiment includes multiple driving tracks 1, multiple brackets 2, and a truss structure 3. The driving tracks 1 are arranged along the length direction of the bridge 9. The bracket 2 is arranged below the driving tracks 1. The bracket 2 includes a bottom support member 21 and a side support member 22. The bottom support member 21 and the side support member 22 form an accommodating space 23. The truss structure 3 is arranged in the accommodating space 23. The bracket 2 is provided with a driving device 4 for driving the bracket 2 to move along the driving track 1.

[0025] The present bridge beam bottom inspection device comprises two running tracks 1, two brackets 2 and a truss structure 3. The running tracks 1 are arranged along the length of the bridge 9, and the bracket 2 is arranged below the running tracks 1. The bracket 2 includes a bottom support member 21 and a side support member 22, forming a storage space 23 for the truss structure 3. Compared with the prior art in which the truss structure 3 is directly arranged above the bracket 2, the clearance occupied by the truss structure 3 and the bracket 2 is reduced, and inspectors can walk on the truss structure 3. The drive device 4 is directly arranged on the bracket 2, which reduces the clearance occupied by the drive device 4 compared to the prior art in which the drive device 4 is directly installed above the support rod. The structure is compact and stable. Preferably, the bottom support member 21 is four bottom support rods connected to form a quadrilateral; the side support members 22 are four side support rods arranged on the bottom support rod.

[0026] In this embodiment, the bracket 2 further includes a top support assembly 5, which is detachably connected to the side supports 22. Compared to the bracket 2 and the truss structure 3 welded together for transportation, the truss structure 3 in the bracket 2 in this embodiment can be removed from the bracket 2 after the top support assembly 5 is removed. The truss structure 3 can then be removed from the bracket 2 and transported separately, and then reassembled at the inspection site, making transportation convenient and loading and unloading simple.

[0027] In this embodiment, a fixed connection seat 6 is provided on the side support member 22, and the top support assembly 5 is detachably connected to the fixed connection seat 6. The fixed connection seat 6 can serve as an installation base for the top support assembly 5.

[0028] In this embodiment, the top support assembly 5 includes a top rod 51 and a reinforcing core 52, wherein the reinforcing core 52 is fixedly connected to the top rod 51. Preferably, the reinforcing core 52 is a solid iron block, which is welded to the top rod 51, threaded holes are drilled in the solid iron block, and then threadedly connected to the fixed connection seat 6 via a threaded connector 10.

[0029] In this embodiment, the push rod 51 is a square tube, an I-beam, or a channel steel.

[0030] In this embodiment, the truss structure 3 comprises multiple sub-trusses, which are connected to form a whole. For example, the sub-trusses are connected end to end to form a whole. This facilitates assembly and disassembly, solving the problem of transport difficulties caused by the excessive length of the truss structure 3. Of course, in other embodiments, the truss structure 3 can also be a telescopic truss structure.

[0031] In this embodiment, two sets of top support assemblies 5 are provided, with the running track 1 positioned between the two sets of top support assemblies 5. The bottom surface of the running track 1 is located between the top surfaces of the top support assemblies 5 and the top surface of the truss structure 3. This further reduces the amount of space encroached by the bracket 2. Specifically, the spacing between the two top support assemblies 5 is greater than the width of the running track 1.

[0032] In this embodiment, the bracket 2 is provided with mounting brackets 7 on opposite sides of the longitudinal direction of the traveling track 1, and the drive device 4 is mounted on the mounting brackets 7. The drive device 4 is suspended below the traveling track 1 and travels along the traveling track 1, which is convenient for installation. Compared with the prior art in which the drive device 4 is directly mounted above the support rod, the drive device 4 is mounted on the side of the bracket 2, further reducing the headroom occupied by the drive device 4.

[0033] In this embodiment, mounting bracket 7 is also provided with a locking device 8 for securing bracket 2. During aerial work, the inspection device must be fixed in a predetermined position. Locking device 8 prevents bracket 2 from sliding along track 1 in conditions such as strong winds, ensuring smooth operation and protecting the safety of operators. Preferably, locking device 8 is a track clamp.
