Description

Technical Field

[0001] The utility model relates to the technical field of magnetic levitation tracks, in particular to auxiliary equipment for positioning a mold sleeve of a magnetic levitation track plate. Background Art

[0002] The track beam is an important part of the maglev track. It is a beam or plate structure with a track functional surface, bearing the train load and transferring it to the supporting structure. In other words, the maglev track beam has the functions of both the beam and the track of a traditional railway. Compared with the operation of traditional rail trains, maglev trains have extremely high requirements for the accuracy of the track beam.

[0003] In the field of high-speed maglev, the distance between the train magnets and the magnets on the track beam directly affects the change in magnetic buoyancy. In order to ensure the smooth development of lift and resistance when the vehicle is floating and landing, and to ensure the driving comfort of the vehicle in the middle section of the line, very strict requirements are placed on the construction accuracy of the maglev track beam. For the track beam of the maglev track, it is generally equipped with a magnet module inside to provide forward driving force and lift required for suspension for the vehicle above. The magnet module and the track beam are installed through a connecting sleeve with an internal thread. Specifically, the connecting sleeve is embedded in the side wall of the track beam in advance. When the magnet module is installed later, the bolts connected to the magnet module are screwed into the corresponding connecting sleeve to achieve installation.

[0004] With the continuous in-depth research on ultra-high-speed maglev rail technology, the application of ultra-high-speed maglev technology has gradually begun to be considered in certain non-railway transportation fields. This requires the construction of test sections to carry out a large number of engineering tests and verifications.

[0005] When the cast-in-place method is used to prepare the test section maglev track beam structure, due to the increase in the number of magnet modules and the number of grooves for installing magnet modules, a large number of connecting sleeves need to be installed and positioned on the groove wall template at one time. In order to improve the efficiency of the project, the length of the track beam cast in place each time should not be too short, which results in a longer axial length and heavier deadweight of the single-side template, and more connecting sleeves need to be installed and positioned on the single-side template. In order to facilitate the batch installation of the connecting sleeves, it is best to lay the template flat for operation. However, for the track beam template with a large length and deadweight, it is inconvenient to lift it in a horizontal state, and it takes a lot of manpower to lay it flat manually. Utility Model Content

[0006] The utility model provides auxiliary equipment for positioning the sleeve of the magnetic levitation track plate mold, so as to solve the problem of high manpower consumption when paving a track beam template with a long length and heavy weight in the prior art, thereby achieving the purpose of reducing manpower consumption and improving work efficiency.

[0007] The utility model is realized by the following technical solutions:

[0008] Auxiliary equipment for positioning the sleeve of the magnetic levitation track plate mold includes a base, a clamping mechanism hinged on the top of the base, and a power device for driving the clamping mechanism to rotate; the clamping mechanism includes a flip piece that is the same width as the top of the base and hinged on the top of the base, and a clamping groove for clamping the template is opened on the top of the flip piece.

[0009] In view of the problem of high manpower consumption when paving long and heavy track beam templates in the prior art, the utility model proposes an auxiliary device for positioning the sleeve of the magnetic levitation track plate mold. When the device is used, the template is lifted vertically and the bottom end is inserted into the clamping groove. The bottom end of the template is clamped by the clamping mechanism, and then the clamping mechanism is driven by a power device to flip the entirety, driving the clamped template to flip synchronously until the template flips to a horizontal state; then the clamping mechanism is released from the template, and the template is pushed horizontally to leave the range of the clamping mechanism.

[0010] During specific use, a device such as a support platform for supporting the template in a horizontal state can be set next to the equipment, so that the template flipped to the horizontal state can lie flat on such a support platform or other devices.

[0011] In addition, after the installation of the connecting sleeve on the formwork is completed, the present application can also push the end of the formwork back into the clamping groove laterally, clamp the end of the formwork again by the clamping mechanism, and drive the clamping mechanism to flip as a whole by the power device, thereby driving the clamped formwork to flip synchronously to a vertical state, making it easier to lift it to the assembly area for subsequent cast-in-place operations.

[0012] This solution solves the problem that the track beam formwork with large length and self-weight requires a lot of manpower to lay flat on the installation components. At the same time, it can overcome the defect that the long length of the formwork makes it inconvenient to lift it in a horizontal state, which makes laying flat more difficult.

[0013] Furthermore, clamping plates are arranged on both side walls of the clamping groove, and a linear drive device is also included for driving the clamping plates to move toward the inside of the clamping groove.

[0014] This solution uses linear drive devices on both sides to drive the two clamping plates to move toward each other, thereby integrally clamping the end of the template entering the clamping groove.

[0015] Furthermore, a first positioning groove is provided on the top surface of the base, and a positioning protrusion capable of entering the first positioning groove is provided at the bottom end of the flip member; when the flip member is located directly above the base, the positioning protrusion abuts against a side groove wall of the first positioning groove close to the hinge edge of the clamping mechanism.

[0016] Since the flipping member rotates around the hinged edge, the positioning protrusion rotates synchronously with the flipping member. When the flipping member is seated on the top of the base, the positioning protrusion abuts against the side wall of the first positioning groove close to the hinged edge of the clamping mechanism, thereby reducing the possibility of the flipping member automatically flipping outward, improving the lateral stability of the flipping member when it is not flipped, and reducing the locking loss of the power device.

[0017] Furthermore, a groove wall on one side of the first positioning groove away from the hinged edge of the clamping mechanism is set as an arc surface, and the arc surface of the groove wall of the first positioning groove is used to ensure that the positioning protrusion can smoothly enter and exit the first positioning groove.

[0018] Furthermore, it also includes a limiting member fixed to a side wall of the base away from the hinged edge of the clamping mechanism, and the top height of the limiting member is higher than the height of the base.

[0019] The limiter can be used to limit the over-rotation of the flip member to the other side away from the hinged edge, and can also limit the flip member laterally, thereby improving the lateral stability of the flip member when it is not flipped.

[0020] Furthermore, a sensing device for sensing the flipping member is disposed on a side surface of the limiting member facing the direction where the clamping mechanism is located; and the sensing device is signal-connected to the power device.

[0021] The flipping piece is sensed by the sensing device on the surface of the limit piece, and then when the power device drives the flipping piece to reset and drives the template on which the connecting sleeve has been installed in batches to return to the vertical state, the sensing signal of the sensing device can provide the power device with a more stable feedback or stop signal.

[0022] Furthermore, the sensing device is a distance measuring sensor, which determines whether the flip member returns to the vertical state by sensing the distance of the object in front.

[0023] Furthermore, the top of the clamping plate is rounded to facilitate the bottom end of the template to smoothly enter the clamping groove.

[0024] Furthermore, a pressure sensor is arranged on the surface of the clamping plate, and the pressure sensor is connected to the linear drive device by signal, and the output of the linear drive device can be controlled by feedback of the sensing data of the pressure sensor.

[0025] Furthermore, the power device is a servo motor, which is conducive to more precise control of the rotation angle of the clamping mechanism.

[0026] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0027] 1. The utility model is an auxiliary device for positioning the sleeve of the magnetic levitation track plate mold, which can realize the laying down and flattening of the template, and can solve the on-site operation problem of the track beam template with long length and heavy weight.

[0028] 2. The utility model is an auxiliary device for positioning the sleeve of the magnetic levitation track plate mold, which solves the problem that the track beam template with large length and dead weight requires a lot of manpower to lay flat, and at the same time overcomes the defect that it is inconvenient to hoist it in a horizontal state due to the large length of the template.

[0029] 3. The utility model is an auxiliary device for positioning the sleeve of the magnetic levitation track plate mold, and can also reset the processed template to a vertical state, so as to facilitate lifting it in a vertical state again for subsequent operations.
