Abstract
The utility model discloses a telescopic boom safety protection device applicable to aerial platform vehicles, which comprises a chain device (9) and a body (8). Pull rods (2) are arranged at the end of the chain device (9), chain holders (7) are arranged on the body (8), pull rod holders (5) are arranged on the pull rods (2), springs are compressed between the chain holders (7) and the pull rod holders (5), and the pull rods (2) in extension can contact with a contact device (1) electrically connected with a vehicle operation stopping signal transmitting device. The telescopic boom safety protection device is capable of protecting safety for aerial platform vehicles in operation when chains or steel wire ropes are broken, and is simple in structure and reliable in performance.
Description
Technical field
The utility model relates to a kind of aerial platform, and particularly relating to a kind of aerial platform is the safety guard of equipment with slide fastener or steel rope telescoping mechanism.
Background technology
Aerial platform is an equipment with slide fastener or steel rope telescoping mechanism, after slide fastener or steel rope have broken, just has very big potential safety hazard if aerial platform works on.
Summary of the invention
The technical matters that the utility model solved provide a kind of can be when the aerial platform operation slide fastener or steel rope carry out safety guard-safeguard after having broken be applicable to aerial platform telescopic boom safety guard.
In order to solve the problems of the technologies described above; the utility model provides is applicable to aerial platform telescopic boom safety guard; comprise chain stretching device and body; the end of described chain stretching device is provided with pull bar; on described body, be provided with the slide fastener seat; be provided with draw-bar seat on described pull bar, length of spring compressed is located between described slide fastener seat and the described draw-bar seat, can collide when described pull bar stretches out one with the car load crash device that sender unit is electrically connected that stops operation.
Described draw-bar seat movable set is rotary with the adjustment nut and the retaining nut that act on described draw-bar seat on described pull bar on described pull bar.
That adopts technique scheme is applicable to aerial platform telescopic boom safety guard, and the normal condition lower spring is compressed between the slide fastener seat and draw-bar seat of chain stretching device and pull rod device.But car load normal operation under this state, the adjustment nut in the adjusting yoke device can change the compression of spring size.In the situation lower spring elongation of chain stretching device fracture, spring pushing drawing rod seat in elongation process moves, and draw-bar seat drives pull bar and moves, and pull bar will be run into crash device, and crash device receives collision alarm and sends the car load signal that stops operation at once.
The utility model be a kind of can be when the aerial platform operation slide fastener or steel rope carry out safety guard-safeguard and simple in structure, dependable performance after having broken be applicable to aerial platform telescopic boom safety guard.
Description of drawings
Fig. 1 is the utility model structure and normal operation scheme drawing;
Fig. 2 is a scheme drawing under the utility model guard mode.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, the end of chain stretching device 9 is provided with pull bar 2, on body 8, be provided with slide fastener seat 7, draw-bar seat 5 movable sets are on pull bar 2, on pull bar 2, be rotary with the adjustment nut 4 and retaining nut 3 that act on draw-bar seat 5, pull bar 2 axially passes spring 6, and spring 6 compression is located between slide fastener seat 7 and the draw-bar seat 5, can collide when pull bar 2 stretches out one with the car load crash device 1 that sender unit is electrically connected that stops operation.
Referring to Fig. 1 and Fig. 2, pull bar 2 axially passes spring 6, restraining spring 6 produces torsional deflection under draw-bar seat 5 and slide fastener seat 7 compress, adjustment nut 4 is screwed in restriction draw-bar seat 5 sway on the pull bar 2 with retaining nut 3, and drives draw-bar seat 5 compression springs 6 when pull bar 2 is subjected to tightening force.Slide fastener seat 7 is fixed on the body 8.When chain stretching device 9 disconnects, spring 6 compression sections are released and will outwards move by pushing drawing rod seat 5, draw-bar seat 5 just is delivered to power on adjustment nut 4 and the retaining nut 3, adjustment nut 4 and retaining nut 3 drive pull bars 2 and move and run into crash device 1, and crash device 1 will send the car load signal that stops operation.
The utility model is a kind of fender guard of breaking that can carry out safety guard-safeguard when the aerial platform operation; this principle of device is simple, and control is convenient, dependable performance; by using this crash device to combine, make car load have higher safety guard-safeguard effect with spring installation.
