Description

Technical Field

[0001] The utility model relates to the technical field of lining trolleys, in particular to a track transmission device of a lining trolley. Background Art

[0002] The lining trolley is a special equipment mainly used for pouring tunnel concrete. Usually, it includes two tracks 200 laid along the direction of the tunnel, sleepers 100 are placed under the tracks 200, and the running wheel assembly 300 rides on the tracks 200. A horizontal beam support seat 400 is axially connected to the two sets of running wheel assemblies 300, and the horizontal beam 500 is arranged along the direction of the track 200 and connected to the horizontal beam support seat 400. When pouring tunnel concrete, the template is squeezed on the inner wall of the tunnel, and the inside of the template is connected to the lining trolley by hydraulic or fixed means. In addition, the running wheel assembly 300 needs to be in a parking state. In order to ensure the support reliability of the lining trolley, several support columns 600 are usually installed under the horizontal beam 500. When the lining trolley is moving, the support columns 600 need to be removed (that is, when the support is not poured).

[0003] At present, the lining trolley in the prior art has the following problems: First, after pouring a section of concrete, when the lining trolley needs to be moved, the track 200 needs to be installed in advance at the front end of the travel direction, that is, the track 200 at the rear end of the travel direction of the lining trolley is moved to the front of the lining trolley and installed, and the transportation is still done manually. In addition, the support column 600 needs to be removed after pouring, which is time-consuming and labor-intensive.

[0004] In addition, in the Chinese invention patent with the patent publication number: CN117823184A, entitled: A self-rail-feeding device for a lining trolley traveling frame and its working method, a hydraulic mechanism is provided for support, and then the traveling wheel assembly (i.e., the traveling rail-feeding mechanism) is used to connect and propel the lining. In fact, the weight of the lining trolley ranges from several tons to dozens of tons, and it is unreliable to rely solely on the support of the hydraulic mechanism.

[0005] Therefore, there is an urgent need to propose a track transmission device for a lining trolley with a simple structure and reliable support. Utility Model Content

[0028] As Figures 2 to 3 As shown, this embodiment provides a track transmission device for a lining trolley, wherein the lining trolley includes a plurality of traveling wheel assemblies 300, a track 200 is arranged at the bottom of the traveling wheel assemblies 300, a plurality of sleepers 100 are arranged at the lower part of the track 200, a horizontal beam support seat 400 is arranged on the traveling wheel assemblies 300; a horizontal beam 500 is arranged on the horizontal beam support seat 400, and the horizontal beam 500 is arranged along the direction of the track 200, and the track 200 is arranged perpendicular to the sleeper 100. It should be noted that the track 200 can be placed directly on the sleeper 100, or it can be bolted. If bolted connection is adopted, the connection needs to be released during track transmission.

[0029] In this embodiment, the rail transmission device of the lining trolley includes a rail lifting mechanism 1 arranged on the traveling wheel assembly 300, and an array of horizontal beam support assemblies 2 arranged at the bottom of the horizontal beam 500. The rail lifting mechanism 1 pulls and lifts the rail 200, and the rail 200 rolls in contact with the lower part of the traveling wheel assembly 300.

[0030] In this embodiment, the horizontal beam support assembly 2 includes a lower connecting seat 21 fixed to the bottom of the horizontal beam 500, a connecting column 22 arranged at the lower part of the lower connecting seat 21, a crossbeam 23 sleeved on the connecting column 22 and rotating and switching along the direction of the track 200 or perpendicular to the track 200, and a hand-cranked jack 24 arranged at the end of the crossbeam 23 in a one-to-one correspondence. The hand-cranked jack 24 is squeezed and supported on the track 200 or the sleeper 100. Before pouring concrete, the crossbeam 23 is rotated so that it is parallel to the track, and the hand-cranked jack 24 is shaken down so that the lower part of the hand-cranked jack 24 is squeezed on the track. In this way, the traditional support column can be replaced, and its installation and disassembly are convenient and reliable. In addition, when the track 200 needs to be moved, the squeezing of the hand jack 24 is released, and the crossbeam 23 is rotated so that the crossbeam 23 is parallel to the sleeper 100, and then the hand jack 24 is shaken down so that the lower part of the hand jack 24 is squeezed on the sleeper 100. In this way, the force of the lining trolley is directly transferred from the track 200 to the sleeper. Since the horizontal beam support assembly 2 is arranged in an array, the force of the lining trolley support can be guaranteed to be reliable.

[0031] In addition, when the horizontal beam support assembly 2 is supported on the sleeper, the lower part of the traveling wheel assembly 300 will be separated from the track. In order to use the traveling wheel assembly 300 to squeeze and drive the track to move forward, the present embodiment is provided with a track lifting mechanism 1, which includes a connecting plate 11 provided on the traveling wheel assembly 300, a threaded adjustment rod 15 provided on the upper part of the connecting plate 11, a hand wheel 14 threadedly sleeved on the threaded adjustment rod 15 and placed on the upper part of the connecting plate 11, a rotating sleeve 16 provided at the bottom of the threaded adjustment rod 15, a front clamping plate 17 and a rear clamping plate 18 mirror-imaged and bolted, and a plurality of squeezing support wheels 19 provided on the inner side of the lower part of the front clamping plate 17 and the rear clamping plate 18. Among them, the squeezing support wheel 19 is rolled sleeved on the track 200, and the upper parts of the front clamping plate 17 and the rear clamping plate 18 are axially connected to the rotating sleeve 16. In addition, a plurality of strip holes 12 are provided on the connecting plate 11, and a connecting screw 13 is sleeved in the strip holes 12. The connecting screw 13 is fixed on the traveling wheel assembly 300. After releasing the connection between the track 200 and the sleeper 100, the horizontal beam support assembly 2 supports and lifts the lining trolley, and uses the hand wheel 14 and the threaded adjustment rod 15 to drive the extrusion support wheel 19 to move upward, so that the track 200 is squeezed on the traveling wheel assembly 300. At this time, the motor of the traveling wheel assembly 300 is used to drive the traveling wheel to rotate and push the track 200 forward. It should be noted that when the horizontal beam support assembly 2 does not support and lift the lining trolley, there may be a certain gap between the extrusion support wheel 19 and the upper inner wall of the track 200, that is, when pouring concrete, the extrusion support wheel 19 has no contact with the upper inner wall of the track 200. In this embodiment, the lining trolley is lifted by the horizontal beam support assembly 2, and the track 200 is lifted by the track lifting mechanism 1, and the traveling wheel assembly 300 is used to drive the movement. After the track is transferred forward for a certain distance, the track and the lining trolley are lowered, so that the force of the lining trolley is transmitted to the track 200 through the traveling wheel assembly 300, and then the cross beam 23 is rotated to park and fix the trolley during pouring. The use process of this embodiment is similar.

[0032] The above embodiments are only preferred embodiments of the present utility model and are not intended to limit the protection scope of the present utility model. Any changes that adopt the design principles of the present utility model and are made through non-creative labor on this basis should fall within the protection scope of the present utility model.
