Description
Technical field
The utility model relates to a kind of extendable conveyor, and in particular, it relates to a kind of fender guard of extendable conveyor.
Background technology
Extendable conveyor is a kind of belt conveyer with telescoping mechanism, it has several mutually sheathed expansion boxs, expansion box is provided with belt conveyor, by slippage free-extension on the length direction of belt feeder between several expansion boxs, regulates the delivered length of belt feeder.
In extendable conveyor use procedure, because expansion box is stretched by driven by motor, when extendable conveyor extends, the expansion box of forefront easily collides operating personal or other objects, cause safety misadventure, usually be all provided with anti-collision switch in the front end of extendable conveyor, in order to control motor stalling, stretching motion stopped in time.
At present, the fender guard of extendable conveyor on the market by being horizontally installed on the crash bar foremost of extendable conveyor, the crash bar that makes be arranged on crash bar forms to the travel switch of the guide piece of after contraction, the spring-return mechanism be connected with guide piece and guiding mechanism end.
But above-mentioned fender guard has following shortcoming: fender guard can only along the length direction of extendable conveyor to after contraction, when extendable conveyor upwards rotate meet other objects time, crash bar cannot shrink, and can cause safety misadventure.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of fender guard increasing the extendable conveyor of extendable conveyor processing safety.
For achieving the above object; the utility model provides following technical scheme: a kind of fender guard of extendable conveyor; comprise expansion box; described expansion box be horizontally arranged with crash bar foremost; described crash bar is connected with the guiding mechanism that crash bar is rotated up and down; described guide piece is connected with the travel switch controlling expansion box and retract, described crash bar can trigger travel switch when up-and-down movement.
As preferably, described guiding mechanism is arranged in frame, and described guiding mechanism comprises rotation section, and described rotation section and expansion box are rotationally connected, and one end of described rotation section protrudes from frame and is fixedly connected with crash bar.
As preferably, described rotation section and expansion box hinged, the axis of described crash bar is positioned at the below of the jointed shaft place horizontal surface of rotation section and expansion box.
As preferably, described rotation section is provided with the first limiting stopper, described expansion box is provided with the second limiting stopper coordinated with the first limiting stopper, the spring that crash bar is resetted is provided with between described first limiting stopper and the second limiting stopper, described spring one end is fixedly connected with the first limiting stopper, and the described spring other end is fixedly connected with the second limiting stopper.
The utility model has following advantage compared to existing technology: when upwards rotation process encounters obstacle to extendable conveyor, and crash bar rotates triggering travel switch, and extendable conveyor is regained, and increases the safety of extendable conveyor operation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is generalized section one of the present utility model;
Fig. 3 is generalized section two of the present utility model.
In figure: 1, the first expansion box; 2, the second expansion box; 21, groove; 22, the second limiting stopper; 23, spring; 24, hinged block; 3, crash bar; 4, guiding mechanism; 41, rotation section; 42, jointed shaft; 43, the first limiting stopper; 5, travel switch; 51, moving contact.
Detailed description of the invention
With reference to accompanying drawing, the utility model is described further.
As shown in Figure 1; extendable conveyor comprises the first expansion box 1, second expansion box 2 and motor (not shown in FIG.); second expansion box 2 is set in the first expansion box 1; electric machine control second expansion box 2 stretches out with in retraction first expansion box 1, and fender guard is the crash bar 3 that the second expansion box 2 front cross is arranged.
As shown in Figure 2, the leading flank of the second expansion box 2 inside is provided with hinged block 24, described hinged block 24 is hinged with rotation section 41, the shape of rotation section 41 is L-type, one end that rotation section 41 is shorter and hinged block 24 pass through bolted splice, the sidewall of the second expansion box 2 is provided with the groove 21 for L-type rotation section 41 activity, groove 21 can make crash bar 3 rotate to the second expansion box 2 bottom, rotation section 41 is made to have larger stroke, prevent rotation section 41 from hitting to groove 21 side, longer one end, rotation section 41 is fixedly connected with the crash bar 3 being horizontally installed on the second expansion box 2 outside through groove 21, the mode be fixedly connected with of rotation section 41 and crash bar 3 is for welding, obstacle is encountered when extendable conveyor upwards rotates, when crash bar 3 is subject to top-down power, crash bar 3 and rotation section 41 are that axle center rotates clockwise with bolt, in rotation process, the moving contact 51 on travel switch 55 is triggered in rotation section 41, travel switch 55 sends a signal to PLC, PLC output signal controls expansion box and retracts, the height of the center shaft of crash bar 3 is lower than the jointed shaft 42 place horizontal surface of rotation section 41 with hinged block 24, obstacle is encountered when the second expansion box 2 to stretch out along the length direction of extendable conveyor or upwards rotates, because the center shaft of crash bar 3 is lower than the articulated position of bolt, the antagonistic force that obstacle provides can make crash bar 3 rotate clockwise along articulated position until touch the moving contact 51 on travel switch 55, travel switch 55 sends a signal to PLC, and PLC output signal controls expansion box and retracts.
As shown in Figure 2, second expansion box 2 inside is provided with the second limiting stopper 22, as shown in Figure 3, guiding mechanism 4 has been bolted the first limiting stopper 43, spring 23 is provided with between first limiting stopper 43 and the second limiting stopper 22, spring 23 one end is fixedly connected with the first limiting stopper 4343, spring 23 other end is fixedly connected with the second limiting stopper 22, crash bar 3 is stressed makes rotation section 41 clickwise rear spring 23 deformation in compression, second expansion box 2 is retracted, crash bar 3 does not stress, first limiting stopper 43 and second spacing between spring 23 discharge deformation power rotation section 41 resetted.
When fender guard uses, second expansion box 2 stretches out forward under the control of motor, in the process of stretching out, crash bar 3 encounters obstacle or people, crash bar 3 is that turning cylinder rotates clockwise with bolt, until by the moving contact 51 of rotation section 41 depression stroke switch 55, then travel switch 55 sends a signal to PLC, PLC controls motor reversal or stall, stop stretching out or being retracted by the second expansion box 2 of the second expansion box 2, prevent the second expansion box 2 from bumping against with obstacle further and cause safety misadventure, if there is operating personal to be sandwiched in crash bar 3 with between the walls, and the second expansion box 2 cannot be regained, crash bar 3 can also press down by operating personal, operating personal is departed from.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
