Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of gantry cranes, in particular to an automatic opening device for a track cover of a gantry crane. Background Art
[0002] The gantry crane trolley track is laid on the ground. In order not to affect the ground vehicles crossing the track vertically, the track surface is usually paved with the ground, but there is still a large gap on both sides of the track to ensure the normal operation of the gantry crane. This causes a large impact when the ground vehicle crosses the track vertically, causing damage to the vehicle and the ground. In order to solve this problem, a cover plate is set on the track to be flush with the ground, leaving no gap or almost no gap, to ensure the vertical crossing of ground vehicles is smooth.
[0003] However, this track cover needs to be opened when the crane is in operation, but relying on people to open and close it at any time is obviously not suitable for use. At the same time, the existing covers lack connecting devices between each other, so that the placement of the covers relative to each other cannot be guaranteed when the covers are opened and closed, affecting the sealing effect of the covers. Utility Model Content
[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide an automatic opening device for the track cover of a gantry crane. Through the provision of a plow-shaped guide frame, guide rollers and supporting cross rollers, when the crane is moving, the plow-shaped guide frame at one end of the bottom beam enters the side front of the running track and gradually pushes the cover downward. Under the action of the supporting cross rollers at the front end of the plow-shaped guide frame, the cover is slowly pried up little by little and moves along the plow-shaped guide frame structure. The guide rollers gradually change the posture position of the cover so that the cover is limited between two rows of guide rollers arranged side by side. After the bottom beam moves away, the cover moves into the track groove along the guide rollers on the plow-shaped guide frame at the other end of the bottom beam, and then covers the upper side of the track, so that the opening and closing of the track cover are completely automatic, no manpower is required, and the usage conditions are met, which can effectively solve the problems in the background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automatic opening device for the track cover of a gantry crane, comprising a bottom cross beam, a movable base is installed on the lower side of both ends of the bottom cross beam, a driving wheel structure is installed on the lower side of the movable base, a plow-shaped guide frame is installed on the opposite sides of the two driving wheel structures, a supporting cross roller is arranged at the tip position of the plow-shaped guide frame, guide rollers are arranged on the inclined side of the plow-shaped guide frame and the same side of the two driving wheel structures, the guide rollers are arranged in two rows opposite to each other, a track is arranged on the lower side of the driving wheel structure, and a cover is laid on the upper side of the track.
[0006] Furthermore, a concrete structure is provided at the lower side of the track, and a pull rod is pre-embedded in the concrete structure at a position corresponding to the track.
[0007] Furthermore, elastic ropes are connected between the lower sides of adjacent cover plates, and the cover plates are located between two vertical rows of guide rollers after being vertically opened.
[0008] Furthermore, the cover plate is a triangular structure, and the lower side of the cover plate is fixedly connected to the elastic rope.
[0009] Furthermore, the track is connected to the concrete structure via the pull rod, and cross bars are fixed to the upper ends of the two rows of guide rollers.
[0010] Furthermore, the cover plate is arranged on the same side of the two driving wheel structures after being vertically opened, and the guide roller is rotatably connected to the plough-shaped guide frame.
[0011] Furthermore, the cover plates are symmetrically arranged on the upper sides of the tracks at both ends of the bottom cross beam.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] The utility model provides a plow-shaped guide frame, a guide roller and a supporting transverse roller, so that when the crane moves, the plow-shaped guide frame at one end of the bottom cross beam enters the side front of the running track and gradually pushes the cover plate downward. Under the action of the supporting transverse roller at the front end of the plow-shaped guide frame, the cover plate is slowly pried up little by little and moves along the plow-shaped guide frame structure. The guide roller gradually changes the posture position of the cover plate, so that the cover plate is limited between two rows of guide rollers arranged side by side. After the bottom cross beam moves away, the cover plate moves into the track groove along the guide roller on the plow-shaped guide frame at the other end of the bottom cross beam, and then covers the upper side of the track, so that the track cover plate is opened and closed completely automatically without manpower, which meets the usage conditions.
[0014] The utility model provides an elastic rope so that when the cover is opened and closed, adjacent cover plates are tightly attached to each other under the elastic force of the elastic rope, thereby avoiding misalignment of the placement positions of adjacent cover plates after the cover plates are opened and closed multiple times, thereby ensuring the sealing effect of the cover plates.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] See also Figure 1-7 The present embodiment provides a technical solution: an automatic opening device for a gantry crane track cover, comprising a bottom cross beam 1, a movable base 2 is installed on the lower side of both ends of the bottom cross beam 1, a driving wheel structure 3 is installed on the lower side of the movable base 2, a plow-shaped guide frame 4 is installed on the opposite sides of the two driving wheel structures 3, a supporting cross roller 10 is arranged at the tip position of the plow-shaped guide frame 4, guide rollers 9 are arranged on the inclined side of the plow-shaped guide frame 4 and the same side of the two driving wheel structures 3, and the guide rollers 9 are arranged in two rows opposite to each other, a track 8 is arranged on the lower side of the driving wheel structure 3, and a cover 7 is laid on the upper side of the track 8.
[0025] like Figure 1-7As shown, when the bottom cross beam 1 moves, the driving wheel structure 3 on the lower side of the bottom cross beam 1 can drive the gantry crane structure to move, and the plow-shaped guide frame 4 on the driving wheel structure 3 faces the moving direction. The plow-shaped guide frame 4 at one end of the bottom cross beam 1 enters the side front of the running track 8 and gradually pushes the cover plate 7 downward. Under the action of the supporting cross roller 10 at the front end of the plow-shaped guide frame 4, the cover plate 7 is slowly pried up little by little and moves along the plow-shaped guide frame 4 structure. The guide roller 9 gradually changes the posture position of the cover plate 7, so that the cover plate 7 is vertically limited between the two rows of guide rollers 9 arranged side by side. In the process, after the bottom cross beam 1 moves away, the cover plate 7 moves into the groove of the track 8 along the guide roller 9 on the plow-shaped guide frame 4 at the other end of the bottom cross beam 1, and then covers the upper side of the track 8, so that the opening and closing of the track 8 cover plate 7 is completely automatic, without manpower, and meets the usage conditions. Because there is an elastic rope 11 between adjacent cover plates 7, the adjacent cover plates 7 are reset under the elastic force of the elastic rope 11 after being opened and closed many times, avoiding misalignment of the adjacent cover plates 7 when they are covered on the upper side of the track 8, thereby ensuring the sealing effect of the cover plates 7.
[0026] A concrete structure 5 is provided at the lower side of the track 8 , and a tie rod 6 is pre-buried in the concrete structure 5 at a position corresponding to the track 8 . The concrete structure 5 can ensure that the track 8 is stably supported, and the tie rod 6 can stably fix the track 8 on the concrete structure 5 .
[0027] An elastic rope 11 is connected between the lower sides of adjacent cover plates 7. After the cover plates 7 are vertically opened, they are between two rows of vertical guide rollers 9. The elastic rope 11 itself has elastic force, so that when the cover plates 7 are opened and closed multiple times, the adjacent cover plates 7 can be tightly pressed together under the action of the elastic force, avoiding misalignment of the cover plates 7 and ensuring the sealing effect of the cover plates 7.
[0028] The cover plate 7 is a triangular structure, and the lower side of the cover plate 7 is fixedly connected to the elastic rope 11. The shape of the cover plate 7 facilitates the opening and closing of the cover plate 7 under the action of the plough-shaped guide frame 4.
[0029] The track 8 is connected to the concrete structure 5 through a pull rod 6. A cross bar is fixed to the upper ends of the two rows of guide rollers 9. The two vertically arranged rows of guide rollers 9 can limit the vertically erected cover plate 7 to prevent the cover plate 7 from tipping over, thereby ensuring the covering effect of the cover plate 7 on the track 8.
[0030] After being vertically opened, the cover plate 7 is arranged on the same side of the two driving wheel structures 3, and the guide roller 9 is rotatably connected to the plough-shaped guide frame 4. When the guide roller 9 rotates, the cover plate 7 can be guided and transported to ensure that the opening and closing of the cover plate 7 are smoother.
[0031] The cover plates 7 are symmetrically arranged on the upper sides of the rails 8 at both ends of the bottom cross beam 1 .
[0032] The working principle of the automatic opening device for the track cover of a gantry crane provided by the utility model is as follows: Figure 1-Figure 7 As shown, when the bottom cross beam 1 moves, the driving wheel structure 3 on the lower side of the bottom cross beam 1 can drive the gantry crane structure to move, and the plow-shaped guide frame 4 on the driving wheel structure 3 faces the moving direction. The plow-shaped guide frame 4 at one end of the bottom cross beam 1 enters the side front of the running track 8 and gradually pushes the cover plate 7 downward. Under the action of the supporting cross roller 10 at the front end of the plow-shaped guide frame 4, the cover plate 7 is slowly pried up little by little and moves along the plow-shaped guide frame 4 structure. The guide roller 9 gradually changes the posture position of the cover plate 7, so that the cover plate 7 is vertically limited between the two rows of guide rollers 9 arranged side by side. In the process, after the bottom cross beam 1 moves away, the cover plate 7 moves into the groove of the track 8 along the guide roller 9 on the plow-shaped guide frame 4 at the other end of the bottom cross beam 1, and then covers the upper side of the track 8, so that the opening and closing of the track 8 cover plate 7 is completely automatic, without manpower, and meets the usage conditions. Because there is an elastic rope 11 between adjacent cover plates 7, the adjacent cover plates 7 are reset under the elastic force of the elastic rope 11 after being opened and closed many times, avoiding misalignment of the adjacent cover plates 7 when they are covered on the upper side of the track 8, thereby ensuring the sealing effect of the cover plates 7.
