[0031] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0032] A high-speed rail track plate demoulding machine, such as Figures 1 to 7 As shown,

[0033] It comprises a working platform 2 installed on the main frame 1, on which two groups of lifting units and two groups of stretching units are symmetrically installed;

[0034] A horizontal moving device 3 is provided on the working platform corresponding to each group of stretching devices, and the horizontal moving device includes a crossbeam 4 and a horizontal driving mechanism 5 that drives the crossbeam to move; the horizontal driving mechanism can adopt a hydraulic cylinder or an electric cylinder. Of course, those skilled in the art can also adopt a screw transmission mechanism or a gear rack transmission mechanism to achieve horizontal drive according to actual needs.

[0035] Each group of the stretching units includes two stretching devices symmetrically arranged on the crossbeam. In an optional embodiment, the stretching device includes a stretching cylinder 6 and a gripper 7 installed at the lower end of the stretching cylinder, the extension rod end of the stretching cylinder is arranged downward, and the gripper is installed at the lower end of the extension rod. Usually, the stretching cylinder adopts an electric cylinder or a hydraulic cylinder.

[0036] The stretching cylinder is used to realize telescopic adjustment, thereby driving the gripper to perform lifting and lowering actions. The gripper can adopt a commonly used mechanism or device in the prior art. Of course, in other implementation schemes, a hook or other structure can also be installed at the lower end of the stretching cylinder, as long as it can hook the door-shaped steel bar at the bottom of the track plate to realize the pulling action.

[0037] Each group of the jacking units includes two jacking devices, and the jacking devices are symmetrically installed below the working platform or symmetrically installed below the crossbeam.

[0038] In the embodiment where the lifting device is symmetrically installed below the working platform:

[0039] Two groups of lifting units have a total of 4 lifting devices, which are arranged at the four corners of the working platform, preferably in a symmetrical arrangement. This design is mainly used for the separation of track plates of the same or similar specifications from steel molds.

[0040] In the embodiment where the lifting device is installed symmetrically below the beam:

[0041] The two lifting devices in each lifting unit are symmetrically installed on both sides of the same beam. With the driving of the horizontal moving device, the lifting device and the stretching device on the same side beam can adjust their positions at the same time, which can better adapt to the working conditions. Under this design, the demoulding machine can better adapt to the demoulding of products of different specifications, with strong adaptability and good versatility.

[0042] In an optional embodiment, a slide seat 8 that slidably cooperates with the crossbeam is provided on the working platform. When the horizontal moving device drives the crossbeam to move, the friction force is small and the crossbeam slides more smoothly.

[0043] The jacking device comprises a vertically arranged jacking cylinder 9. Usually, the jacking cylinder adopts an electric cylinder or a hydraulic cylinder. In an optional embodiment, the extension rod of the jacking cylinder is arranged downward, and a support plate 10 is installed at the lower end of the extension rod.

[0044] In the prior art, when a demoulding machine is used to demould the high-speed rail track slab, the forces between the high-speed rail track slab and the steel mold may be different at different locations, or the forces applied by the pulling mechanism of the demoulding machine are not balanced enough, etc., the high-speed rail track slab and the steel mold cannot always be kept in a vertical state for demoulding. When there is a displacement difference at both ends of the high-speed rail track slab, the pulling mechanism on the existing demoulding machine is a rigid fixed structure, the demoulding equipment is more likely to be damaged, and the track slab is also more likely to be damaged.

[0045] In view of the above situation, in an optional embodiment, a floating control mechanism 11 is provided on the crossbeam corresponding to the stretching device to reduce the harm caused by the workpiece and the steel mold being separated during the stretching process of the stretching device, thereby avoiding damage to the demoulding machine structure.

[0046] The extension rod of the stretching cylinder extends downward through the through hole on the crossbeam, and the upper end of the cylinder barrel of the stretching cylinder is hinged on the main frame. The floating control mechanism includes a base 12 arranged correspondingly on the crossbeam, and a sleeve 13 sleeved on the outside of the cylinder barrel of the stretching cylinder. The sleeve is generally fixed on the outside of the cylinder barrel, and an elastic pulling element 14 is provided between the cylinder barrel and the base on each side. The pulling element generally adopts a tension spring, which symmetrically forms a pulling force on the outside of the sleeve, which plays a role in maintaining the cylinder barrel while allowing the cylinder barrel (stretching cylinder) to have a certain floating space.

[0047] In addition, a ball seat assembly is provided at the cylinder head 29 at the lower end of the cylinder barrel. Specifically, the ball seat assembly includes a lower ball seat 15 fixed on the cross beam and an upper ball seat 16 fixed at the lower end of the cylinder head. The upper and lower ball seats are matched by spherical surfaces to allow the stretching cylinder to float left and right to a certain extent. Such a floating structure design can effectively avoid damage to the demolding machine structure during the demolding process.

[0048] The upper ball seat specifically includes an upper ball seat body 17 and a wing 18 extending outward from the upper end of the upper ball seat body. The lower ball seat specifically includes a lower ball seat body 19, on which a concave spherical groove 20 is provided, and a ball head structure 21 at the lower end of the upper ball seat body cooperates with the groove.

[0049] An L-shaped anti-slip element is provided on the lower ball seat corresponding to the flank of the upper ball seat. The anti-slip element includes a connecting portion 22 and an inward shielding portion 23 on the connecting portion. When fixing the anti-slip element, a screw 24 can be passed through the connecting portion to connect to the lower ball seat.

[0050] A limiting groove 25 is formed between the shielding part and the lower ball seat body. Under normal circumstances, there are gaps between the side wing and the inner wall of the shielding part, the inner wall of the connecting part and the upper end surface of the lower ball seat body, so that the side wing has a certain floating amount in the limiting groove, and the floating amount of the side wing (upper ball seat) can be limited by the anti-slip element, which plays an excellent limiting role.

[0051] The high-speed rail track plate and steel mold that have been put into place arrive at the demoulding station. A pulley 27 can be installed at the lower end of the main frame to move the main frame to the top of the demoulding station along the fixed steel beam 28.

[0052] According to different track plate models, two sets of horizontal moving devices are used simultaneously or separately to adjust the position of the stretching device (and the lifting device). Four sets of lifting devices extend downward to contact the side mold of the track plate steel mold (and continue to extend to the set force value and stop), so that the lifting device and the track steel mold 26 form a relatively vertical state.

[0053] Taking the use of grippers at the lower end of the stretching device as an example, 4 sets of stretching devices extend downward, and the grippers are in an open state at this time. When the grippers reach the position where they can hold the gate-shaped steel bars at the bottom of the track plate, the grippers are closed, and each gripper will hold multiple gate-shaped steel bars on the track plate at the same time. Then the 4 sets of stretching devices begin to stretch upward (as needed, tension sensors, contact sensors, etc. can be set on the stretching devices. When the set force value is sensed, the corresponding stretching device stops moving until the tension sensors on the 4 sets of stretching devices all reach the set force value. Then, each stretching device continues to stretch upward synchronously according to the displacement to ensure that the track plate is demoulded synchronously at all locations as much as possible).

[0054] The track plate demoulding operation is realized by utilizing the reverse force of the jacking device and the stretching device until the track plate is pulled out of the steel mold. When the track plate is completely separated from the steel mold, that is, when the track plate surface and the upper edge of the steel mold reach a certain distance, the jacking device retracts (disengages from the steel mold side mold), and then the main frame moves to the location where the track plate needs to be stored through the fixed steel beam, and the stretching device extends downward. When the track plate contacts the ground or the support, the sensor contacts the concrete at the bottom of the track plate, and the gripper is opened to put down the track plate. At this time, the stretching device stretches upward and returns to the original position. After that, the main frame moves to the demoulding station through the fixed steel beam to repeat the operation.

[0055] The demoulding machine provided by the invention is suitable for a track plate production line using an assembly line method and can be directly installed on the production line. It can realize demoulding and transfer of the track plates, save manpower, and improve production efficiency. In addition, it can maximize the vertical demoulding of the track plates and the steel molds, avoid damage to the track plates, and ensure the quality of the track plates. At the same time, the demoulding machine is in a good stress condition, which can effectively protect the demoulding machine and avoid damage to its structural parts.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
