Abstract
The utility model discloses a manual rail clamping device provided with a limit switch, relates to hoisting machinery, and solves the technical problem of potential safety hazards existing when a conventional manual rail clamping device is operated on the ground. The manual rail clamping device comprises rail tongs, a rail tong bracket, a connecting base, a hinge pin, a handle, a screw rod and a shaft sleeve, wherein the rail tongs are mounted on the rail tong bracket through the hinge pin; the rail tong bracket is fixed with the connecting base, and the connecting base is connected with a trolley frame or a lower beam of a portal crane; the screw rod is matched with the shaft sleeve fixed on the rail tongs, and the handle is connected with the screw rod; and a limiting switch base is mounted on the connecting base, a limit switch is mounted on the limiting switch base, and a signal line of the limit switch is transmitted to a cab of a crane. According to the manual rail clamping device, the limiting switch is added, so that a driver can know whether the crane is in a work state, so that the safety and the reliability of the outdoor crane are improved.
Description
Technical field
The utility model relates to elevator machinery, particularly a kind of Manual rail clamping device for outdoor crane in bridge type, semi-goliath crane, transfer crane and monkey.
Background technology
The structure of existing Manual rail clamping device as depicted in figs. 1 and 2, comprising: rail tongsrail clamp 1, rail tongsrail clamp support 2, Connection Block 3, bearing pin 6, handle 7, leading screw 8, axle sleeve 9.During turning handle 7, by leading screw 8, drive rail tongsrail clamp 1 action, realize the operation of gripper rail or relieving track.When the shortcoming of this structure is ground staff's M/C, in driver's cab, there is no signal transmission, do not know that hoisting crane is in what state, poor stability.
Summary of the invention
The purpose of this utility model is intended to overcome the shortcoming of prior art, and a kind of Manual rail clamping device with limit switch is provided, and while solving existing Manual rail clamping device terrestrial operation, there is no signal transmission in crane cabin, has the technical matters of potential safety hazard.
The utility model is achieved through the following technical solutions:
A kind of Manual rail clamping device with limit switch, comprise: rail tongsrail clamp, rail tongsrail clamp support, Connection Block, bearing pin, handle, leading screw, axle sleeve, rail tongsrail clamp is arranged on rail tongsrail clamp support by bearing pin, rail tongsrail clamp support is fixed with Connection Block again, Connection Block is connected with trolley frame or door machine cross sill, leading screw coordinates with the axle sleeve being fixed on rail tongsrail clamp, and handle is connected with leading screw; It is characterized in that: on described Connection Block, limit switch base is installed, mounting limit switch on limit switch base, the signal wire (SW) of limit switch transfers to crane cabin.
The utility model compared with prior art, owing to having increased limit switch, hoisting crane is when needs gripper rail or relieving track, pull handle, limit switch action, whether driver just can understand hoisting crane in running order, and when hoisting crane is during in off working state, hoisting crane or dolly can be fixed on the ad-hoc location of factory building reliably.So improved the safe reliability of outdoor crane.
Accompanying drawing explanation
Fig. 1 is existing Manual rail clamping device structural representation (front view);
Fig. 2 is the left view of Fig. 1;
Fig. 3 is structural representation of the present utility model (front view);
Fig. 4 is the left view of Fig. 3.
Below in conjunction with accompanying drawing, by preferred embodiment, the utility model is elaborated.
The specific embodiment
As shown in Figure 3,4, a kind of Manual rail clamping device with limit switch, comprise: rail tongsrail clamp 1, rail tongsrail clamp support 2, Connection Block 3, bearing pin 6, handle 7, leading screw 8, axle sleeve 9, rail tongsrail clamp 1 is arranged on rail tongsrail clamp support 2 by bearing pin 6, rail tongsrail clamp support 2 is fixing with Connection Block 3 again, Connection Block 3 is connected with trolley frame or door machine cross sill, and leading screw 8 coordinates with the axle sleeve 9 being fixed on rail tongsrail clamp 1, and handle 7 is connected with leading screw 8; Mounting limit switch seat 4 on described Connection Block 3, mounting limit switch 5 on limit switch base 4, the signal wire (SW) of limit switch 5 transfers to crane cabin.
When hoisting crane or dolly need to enter mode of operation, clockwise direction turning handle 7, handle 7 drives leading screws 8 (or to the right) movement left, and axle sleeve 9 to the right (or left) is mobile, makes rail tongsrail clamp (or left) movement to the right, throw off track, meanwhile, axle sleeve 9 drives rail tongsrail clamp 1 to rotate around bearing pin 8, and the upper end of rail tongsrail clamp 1 contacts with limit switch 5, give driver's cab transmitted signal, hoisting crane can be started working.If hoisting crane will be converted into off working state from mode of operation, after quitting work, hoisting crane is parked in factory building correct position, anticlockwise direction turning handle 7, limit switch 5 is separated with rail tongsrail clamp 1, rail tongsrail clamp 1, in clamp position, is given driver's cab transmitted signal, shows that hoisting crane is fixed safely.
