Description

Technical Field

[0001] The invention discloses an automatic deviation-correcting guide device for crawler-type pushing equipment, and belongs to the field of bridge construction equipment. Background Art

[0002] As the requirements for large-scale, factory-based, standardized and automated bridge construction are becoming increasingly higher, rapid bridge construction technology has developed rapidly. Top-pushing construction technology, rotating construction technology, mobile formwork installation construction technology, etc., are not restricted by hydrogeological conditions, and can achieve factory prefabrication and on-site rapid installation, shortening construction period and reducing costs. Among them, rapid construction methods represented by top-pushing construction technology are widely used in urban highway bridges.

[0003] The current construction method has the following disadvantages:

[0004] 1. The jacking equipment needs manual mechanical correction, which makes the operation difficult and has low safety.

[0005] 2. The construction process consumes a lot of manpower, requires a lot of equipment and machinery, and has high costs. Summary of the invention

[0006] In view of the deficiencies in the prior art, the present invention aims to provide an automatic deviation-correcting guide device for track-propelling equipment.

[0007] In order to achieve the above object, the present invention is implemented through the following technical solutions:

[0008] A crawler pushing equipment automatic deviation correction guide device comprises a crawler pushing equipment, wherein a crawler pushing equipment stop beam is respectively provided on both sides of the crawler pushing equipment, and a plurality of hydraulic adjustment mechanisms are provided on opposite sides of the two crawler pushing equipment stop beams, and the output ends of the plurality of hydraulic adjustment mechanisms are connected to a guide frame, a box beam is placed on the crawler pushing equipment, and a fixed guide support is provided on one side of the bottom of the box beam, and the fixed guide support is slidably connected to the outer side of the guide frame.

[0009] Furthermore, a crawler pushing device stop beam pull rod is connected between the two crawler pushing device stop beams.

[0010] Furthermore, a smooth layer is provided on the outer side of the guide frame, and the smooth layer is made of stainless steel.

[0011] Furthermore, the fixed guide support is a maintenance vehicle rail base installed at the bottom of the box beam.

[0012] Furthermore, a displacement sensor is installed on the guide frame or the fixed guide support, and the displacement sensor is connected to the hydraulic adjustment mechanism and the electric control box.

[0013] Beneficial effects of the present invention:

[0014] The present invention has a simple structure, is safe and convenient to operate, has a limit function, is more conducive to the adjustment of dimensional accuracy, and does not require excessive human intervention during operation. The displacement adjustment device automatically adjusts according to the data provided by the displacement sensor to ensure the spacing between the guide frame and the jacking device. The hydraulic mechanism used to adjust the spacing has a low cost and is easy to use.

[0015] The present invention aims to solve the problem of pushing offset in the construction process of traditional crawler-type pushing equipment, thereby improving work efficiency, reducing construction costs, reducing the input of manpower and material resources, and improving the accuracy of crawler-type pushing displacement.

[0016] The present invention can form a slot structure with a U-shaped notch on the side of the guide frame through the design of the positioning mechanism. After the box beam is adjusted, the stability of the box beam can be improved by the connection between the U-shaped notch and the fixed guide support.

[0017] Through the design of the driving member, the present invention ensures that in the process of the box girder moving along the guide frame with the fixed guide support, the fixed guide support will drive the extrusion block 1 and the extrusion block 2 to move synchronously as the fixed guide support moves. The extrusion block 1 and the extrusion block 2 will squeeze the inclined panel 2 and the inclined panel 1 that penetrate to the top of the guide frame. However, because the extrusion block 2 is longer than the extrusion block 1, the extrusion block 2 will first contact the inclined panel 1 on the guide block to be matched, trigger the limit member first, and then release the limit of the guide block by the limit member, so that when the extrusion block 1 and the inclined panel 2 are subsequently linked, the guide block is in a movable state.

[0018] The present invention adopts the design of the limiting piece, and the extrusion block two contacts with the inclined plate one, and squeezes the inclined plate one on the guide block. The inclined plate one is squeezed and descended under the action of the inclined surface, and the inclined plate one drives the inclined surface block to descend at the same time. The inclined surface block pushes the inclined surface seat to move linearly through the squeezing of the inclined surface, and the inclined surface seat moves and pushes a plurality of inclined surface pushing members to move through the storage groove and squeeze into the guide inclined surface on the plug-in groove, thereby pushing the limiting plate to rise vertically, so that the bottom end of the limiting plate is pulled out from the guide block inside the guide frame, and the limiting of the guide block is released.

[0019] The present invention adopts the design of the linkage part, so that the extrusion block 1 is squeezed together with the inclined panel 2 on the guide block, and then the bottom of the inclined panel 2 squeezes the inclined groove to make the guide block stored in the guide frame. Then, when the fixed guide support moves to a certain position on one side of the guide frame, the two guide blocks corresponding to that position will shrink inside the guide frame, so that several guide blocks on the side of the guide frame can form a U-shaped notch slot structure.

[0020] Through the design of the shielding component of the present invention, during the descent of the inclined plane block, the inclined plane block will pull the traction rope, and the traction rope will pull the movable plate to be moved and stored in the accommodating groove. During the movement of the movable plate, the inclined plane cover plate connected by the spring hinge on the top of the movable plate will be squeezed together with the triangular prism fixed on the inner wall of the opening. The inclined plane will cause the inclined plane cover plate and the triangular prism to rotate and open due to the squeezing of the inclined plane. At the same time, the inclined plane cover plate will pull the slider in the spring groove through the traction rope connected to the inclined plane to squeeze the reset spring.

[0021] The present invention adopts the design of the card bead groove and the spring card bead. Since the length of the extrusion block two is longer than that of the extrusion block one, each time the extrusion block two will squeeze and trigger three inclined panels one, and the extrusion block one will squeeze and trigger two inclined panels two, so that one more guide block will be released from the restriction each time. Moreover, through the abutment limit between the card bead groove and the spring card bead, the abutment force and the friction force are used to reduce the possibility of movement of the guide block and improve the stability of the device.
