Description

Technical Field

[0001] The utility model belongs to the technical field of jacking devices, and particularly relates to a steel structure pipe gallery jacking device. Background Technique

[0002] A steel structure pipe gallery is a large-scale framework composed of continuous pipe gallery frames (beams), rows of floor-standing columns, and various bracings. Its basic structural cross-section is in the shape of "∏". The pipe gallery structure can be single-layer or double-layer, used to support rows of various pipelines, and is widely used in petrochemical production plants. The steel structure pipe gallery is usually welded by various specifications of steel sections, steel section components, and connecting gusset plates, and generally also has walkways, railings, and ladders to meet the needs of operating and maintaining pipelines and valves.

[0003] Currently, during the construction of steel structure projects, it is prone to be restricted by space. For example, when constructing in restricted spaces such as under high-voltage lines, it is impossible to use lifting equipment for hoisting. Therefore, currently, assembly is carried out outside the area, and then the pipe gallery steel structure is jacked and moved to the predetermined position by an on-rail heavy object pusher to complete the construction.

[0004] For example, the patent application number 201310547285.6 discloses an ultra-long steel member sliding and jacking system and its sliding method. Its sliding and jacking system simplifies the sliding equipment for ultra-long and overweight steel structures, and completes the sliding through a simple sliding and jacking device and a crawler.

[0005] In actual use, two steel rails and two sets of pushers are usually used, such as the shield machine subway passing station pusher device disclosed in the patent application number 201520449486.7. The on-rail heavy object pusher consists of a clamping pliers and a pusher oil cylinder. When using two sets of pushers, there will be a situation where they are not synchronized, mainly because there is no connection between the two sets of pushers, and the positional relationship between them cannot be guaranteed. Moreover, in order to ensure clamping, the clamping pliers (clamping cylinder) are provided with a T-shaped through groove, and it needs to be moved in from one side of the track during installation. Content of the Utility Model

[0006] In view of the above technical problems, the utility model provides a steel structure pipe gallery jacking device. The jacking device is provided with a pair of inner pressing blocks and a pair of outer pressing blocks on the clamping guide rail to ensure that they are on the same straight line. During installation, it can be directly placed on the clamped track, which is convenient for installation.

[0007] In order to solve the above technical problems, the technical solution adopted by the utility model is as follows:

[0008] A steel structure pipe gallery jacking device includes a clamping guide rail and a mounting plate. A jacking cylinder is arranged between the clamping guide rail and the mounting plate. A pair of connecting ears are arranged on the mounting plate. A pair of inner pressing blocks and a pair of outer pressing blocks are slidably connected to the clamping guide rail. The pair of inner pressing blocks are located between the pair of outer pressing blocks. The opposite surfaces of the inner pressing blocks and the outer pressing blocks are both flat surfaces. The pair of outer pressing blocks are connected by a first telescopic cylinder, and the two ends of the first telescopic cylinder are respectively fixedly connected to the corresponding outer pressing blocks. The pair of inner pressing blocks are connected by a driving mechanism, and the driving mechanism drives the pair of inner pressing blocks to move relatively or away from each other.

[0009] The driving mechanism includes a driving cylinder and a driving plate. The cylinder body of the driving cylinder is fixedly connected to the clamping guide rail. The driving plate is fixedly connected to the piston rod of the driving cylinder. The two ends of the driving plate are respectively hinged to the corresponding inner pressing blocks through connecting rods. The telescopic movement of the driving cylinder drives the pair of inner pressing blocks to move relatively or away from each other.

[0010] The jacking cylinder is connected with a support track wheel assembly.

[0011] The support track wheel assembly includes a connecting plate and a pair of track wheels. The pair of track wheels are rotatably connected to the connecting plate. The connecting plate is fixedly connected to the cylinder body of the jacking cylinder.

[0012] A connecting sleeve fixedly connected to the cylinder body of the jacking cylinder is arranged on the connecting plate. A fixing set screw is connected to the connecting sleeve through a threaded through hole.

[0013] A connecting shaft connected to the track wheel is arranged on the connecting plate. The track wheel is rotatably connected to the connecting shaft and can move along the connecting shaft. A first adjusting ring and a second adjusting ring are connected to the connecting shaft by threads, and the track wheel is located between the first adjusting ring and the second adjusting ring.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] By driving the pair of inner pressing blocks to move away from each other and driving the pair of outer pressing blocks to move through the telescopic movement of the first telescopic cylinder, the opposite surfaces of the inner pressing blocks and the outer pressing blocks are both flat surfaces, so as to clamp the corresponding track. And since the pair of inner pressing blocks and the pair of outer pressing blocks are both slidably connected to the clamping guide rail, it can ensure that the clamping points of the two are on the same straight line, reducing or avoiding the existing deviation.

[0016] After moving, by driving the pair of inner pressing blocks to move away from each other, repositioning can be carried out, and then by driving the pair of outer pressing blocks to move relatively to clamp the track. That is, every time after moving and then clamping, repositioning and clamping can be carried out. Brief Description of the Drawings

Specific embodiments

[0024] The technical solutions in the embodiments of the present utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0025] As Figures 1-6 shown, a steel structure pipe gallery jacking device includes a clamping guide rail 1 and a mounting plate 2. A jacking cylinder 3 is provided between the clamping guide rail 1 and the mounting plate 2; both ends of the jacking cylinder 3 are fixedly connected to the clamping guide rail 1 and the mounting plate 2 respectively. The jacking cylinder 3, the clamping track 18 and the mounting plate 2 are in an "I" shape, that is, both the jacking cylinder 3 and the clamping track 18 and the jacking cylinder 3 and the mounting plate 2 are vertically connected.

[0026] A pair of connecting ears 4 are provided on the mounting plate 2; each connecting ear 4 is composed of two vertical plates, and pin holes are opened on the two vertical plates and have a certain interval. A corresponding connecting part 20 is provided on the steel structure pipe gallery 19; the connecting part 20 is hinged to the corresponding connecting ear 4. Due to the certain interval between the two vertical plates, the mounted plate 2 still has a certain amount of movement after hinging.

[0027] A pair of inner pressing blocks 5 and a pair of outer pressing blocks 6 are slidably connected to the clamping guide rail 1, and the pair of inner pressing blocks 5 are located between the pair of outer pressing blocks 6; the opposite surfaces of the inner pressing blocks 5 and the outer pressing blocks 6 are both flat surfaces, that is, the contact surfaces with the clamped rail 18 are flat surfaces. Two rails 18 can be respectively clamped by the pair of inner pressing blocks 5 and the pair of outer pressing blocks 6. And due to the arrangement of the clamped rail 18, it can be ensured that the two are on the same straight line after clamping, reducing deviation.

[0028] The pair of outer pressing blocks 6 are connected by a first telescopic cylinder 7, and the two ends of the first telescopic cylinder 7 are respectively fixedly connected to the corresponding outer pressing blocks 6; the pair of inner pressing blocks 5 are connected by a driving mechanism, and the pair of inner pressing blocks 5 are driven to move relatively or away from each other through the driving mechanism.

[0029] During installation, the clamping guide rail 1 is directly placed on the two rails 18 to be clamped; then the pair of inner pressing blocks 5 are driven by the driving mechanism to move away from each other, so that the two inner pressing blocks 5 respectively abut against the inner sides of the two rails 18, and the contact surfaces of the two inner pressing blocks 5 with the rail 18 are flat surfaces. Therefore, after the two inner pressing blocks 5 respectively abut against the inner sides of the two rails 18, it can be ensured that the clamping guide rail 1 and the rail 18 are basically perpendicular to each other.

[0030] Then, the first telescopic cylinder 7 contracts, driving the two outer pressing blocks 6 to move inward, so that the two inner pressing blocks 5 respectively abut against the outer sides of the two rails 18; thus, the two rails 18 can be clamped by the pair of inner pressing blocks 5 and the outer pressing blocks 6. At the same time, since the cylinder block of the first telescopic cylinder 7 is not connected to the clamping guide rail 1; therefore, it can move freely. That is, when it contracts, it may drive one of the outer pressing blocks 6 to move inward. After the outer pressing block 6 contacts the outer side of the corresponding rail 18, as it continues to contract, it drives the other outer pressing block 6 to move inward until it contacts the outer side of the corresponding rail 18. This structural setting that the cylinder block of the first telescopic cylinder 7 is not connected to the clamping guide rail 1 is to ensure that the two outer pressing blocks 6 can both abut against the outer sides of the corresponding rails 18.

[0031] Finally, the connecting part 20 on the steel structure pipe gallery 19 is hinged to the corresponding connecting ear 4.

[0032] After the installation is completed, it is in the above clamping state; the pushing cylinder 3 extends to push the mounting plate 2 and the corresponding steel structure pipe gallery 19 forward along the track 18 until the pushing cylinder 3 is fully extended. Then, the driving mechanism drives a pair of inner pressing blocks 5 to move relative to each other (inward), the first telescopic cylinder 7 extends, and drives the two outer pressing blocks 6 to move outward, that is, it is not in the clamping state at this time; then the pushing cylinder 3 retracts to drive the clamping track 18 to move forward until the pushing cylinder 3 is fully retracted. Finally, repeat the clamping process in the above installation steps to make it in the above clamping state, and again extend the pushing cylinder 3 to push the mounting plate 2 and the corresponding steel structure pipe gallery 19 forward along the track 18. Repeating the above operating steps can realize the movement of the steel structure pipe gallery 19 along the track 18.

[0033] Furthermore, the driving mechanism includes a driving cylinder 8 and a driving plate 9; the cylinder body of the driving cylinder 8 is fixedly connected to the clamping guide rail 1; the driving plate 9 is fixedly connected to the piston rod of the driving cylinder 8; both ends of the driving plate 9 are respectively hinged to the corresponding inner pressing blocks 5 through connecting rods 10; that is, the telescopic movement of the driving cylinder 8 drives a pair of inner pressing blocks 5 to move relative to each other or away from each other.

[0034] Furthermore, a support track wheel assembly is connected to the pushing cylinder 3. The support track wheel assembly includes a connecting plate 11 and a pair of track wheels 12; the pair of track wheels 12 are rotatably connected to the connecting plate 11; the connecting plate 11 is fixedly connected to the cylinder body of the pushing cylinder 3.

[0035] When the pushing cylinder 3 retracts to drive the clamping track 18 to move forward, the two track wheels 12 can be used to ensure that the clamping track 18 and the two clamped tracks 18 are basically perpendicular to each other during the movement.

[0036] Furthermore, for the convenience of installation, a connecting sleeve 13 fixedly connected to the cylinder body of the pushing cylinder 3 is provided on the connecting plate 11; a fixing set screw 14 is connected to the connecting sleeve 13 through a threaded through hole. After the connecting sleeve 13 is sleeved on the cylinder body of the pushing cylinder 3, the connecting sleeve 13 can rotate relative to the cylinder body of the pushing cylinder 3; it is necessary to tighten the fixing set screw 14, and the fixing set screw 14 passes through the threaded through hole and is fixedly connected to the cylinder body of the pushing cylinder 3. During installation, the fixing set screw 14 can be loosened first, and after the clamping guide rail 1 is placed on the two tracks 18 to be clamped and the two track wheels 12 are connected to the corresponding tracks 18, then tighten the fixing set screw 14.

[0037] Furthermore, in order to ensure that a pair of track wheels 12 can adapt to two tracks 18 with different spacings; therefore, a connecting shaft 15 connected to the track wheels 12 is provided on the connecting plate 11, the track wheels 12 are rotatably connected to the connecting shaft 15 and can move along the connecting shaft 15, and the connecting shaft 15 is a round shaft; a first adjusting ring 16 and a second adjusting ring 17 are connected to the connecting shaft 15 by threads, and each track wheel 12 is respectively located between the corresponding first adjusting ring 16 and second adjusting ring 17.

[0038] Place the clamping guide rail 1 on the two rails 18 to be clamped. Drive a pair of inner pressing blocks 5 to move away from each other through the driving mechanism, so that the two inner pressing blocks 5 respectively abut against the inner sides of the two rails 18. Then, adjust the positions of the two track wheels 12 according to the distance between the two rails 18, so that the two track wheels 12 can be placed on the corresponding rails 18. After adjustment, rotate the respective track wheels 12 to be located on the corresponding first adjusting ring 16 and second adjusting ring 17 respectively (and leave a certain gap without affecting the rotation of the track wheels 12), so that the first adjusting ring 16 and the second adjusting ring 17 limit the axial movement of the corresponding track wheels 12;

[0039] Only the preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the above embodiments.
