Description
Technical Field
The utility model belongs to the technical field of the glass processing equipment, a monkey walking stop device is related to.
Background
The crane refers to a multi-action hoisting machine for vertically lifting and horizontally carrying heavy objects within a certain range, which is also called a crown block, a crane, a gantry crane and a crane, and a bridge crane is usually adopted to transport glass in a workshop, so that the bridge crane needs to be installed at the upper part of the workshop, and the running span is large. Due to the limitation of workshop space, the lower part of the crane operation section sometimes has to be used for stacking articles or used as other operation areas, so that the operation of the crane has the danger of rubbing the articles and personnel below the crane, and in order to avoid unnecessary loss, a limiting device is required to be arranged on the crane to divide the operation section, so that the trolley can automatically stop when the trolley cannot reach the area boundary, and the trolley operation section is controlled to avoid cross operation.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a monkey walking stop device to the above-mentioned problem that prior art exists, the utility model aims to solve the technical problem that increase a dolly walking stop device on current wherein machine to control the dolly operation interval, avoid cross operation.
The purpose of the utility model can be realized by the following technical proposal: a travelling limiting device for a crane trolley comprises a crane trolley and a trolley running on the trolley, and is characterized in that a mounting frame is fixed on one side of the trolley, and a first electric cylinder and a second electric cylinder are vertically fixed in the middle of the mounting frame; a connecting rod is fixed on one side of the trolley, which is close to the mounting rack, one end of the connecting rod is fixed on the trolley, and a cross switch is fixed on the other end of the connecting rod; the device also comprises a power adapter, a controller and a remote controller, wherein the first electric cylinder and the second electric cylinder are electrically connected with the controller which is electrically connected with the power adapter; the power adapter is connected with a power supply; the remote controller can control the extension and contraction of the first electric cylinder and the second electric cylinder through the controller.
The utility model has the advantages that:
the device can control the running interval of the trolley, and further, an operation area and a safety area are cut out below the crane, so that unnecessary danger caused by cross operation is avoided. Meanwhile, the free switching of the operation between the whole area and the limited area under the controllable condition of the bridge crane trolley under the special condition can be met.

In the figure, 1, a cart; 2. a trolley; 21. a connecting rod; 22. a cross switch; 3. a mounting frame; 4. a first electric cylinder; 5. a second electric cylinder.
Detailed Description
The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
As shown in fig. 1 and 2, a travelling limiting device for a crane trolley comprises a crane trolley 1 and a trolley 2 running on the trolley 1, wherein a mounting frame 3 is fixed on one side of the trolley 1, and a first electric cylinder 4 and a second electric cylinder 5 are vertically fixed in the middle of the mounting frame 3; a connecting rod 21 is fixed on one side of the trolley 2 close to the mounting rack 3, one end of the connecting rod 21 is fixed on the trolley 2, and a cross switch 22 is fixed at the other end of the connecting rod 21; the device also comprises a power adapter, a controller and a remote controller, wherein the first electric cylinder 4 and the second electric cylinder 5 are electrically connected with the controller which is electrically connected with the power adapter; the power adapter is connected with a power supply; the remote controller can control the extension and contraction of the first electric cylinder 4 and the second electric cylinder 5 through the controller.
The working principle is as follows: the limiting device is arranged in the middle of a crane cart 1, when a certain side area below a crane is provided with stacked articles or used as other temporary operation areas, a trolley 2 can be driven to the other side far away from the area, then a remote controller is in butt joint with a controller, and the controller controls a first electric cylinder 4 and a second electric cylinder 5 to extend outwards, at the moment, if the trolley 2 runs through one of the electric cylinders, a cross switch 22 on the trolley 2 is shifted by a push rod of the electric cylinder, so that the trolley 2 is shifted down and slowly runs until the trolley passes through the other electric cylinder, the cross switch 22 is shifted again, and the trolley 2 stops, so that the trolley 2 can only run in the area and cannot enter the other side, and unnecessary danger caused by the crossing of the operation areas can be avoided; when the regional limitation of the operation of the trolley 2 needs to be removed due to production needs, the push rods of the first electric cylinder 4 and the second electric cylinder 5 can be controlled to retract through the remote controller again, the operation of the trolley 2 on the crane cart 1 is not limited, and the trolley can operate in the whole region, so that the crane can be switched between two working states of the limited regional operation and the whole regional operation very conveniently. By using the remote controller, the examination and approval system can be adopted, so that danger caused by easy removal of a limited area is avoided.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions may be made by those skilled in the art to the specific embodiments described without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
