Abstract
The utility model discloses an automatic reverse device for outrigger and oil cylinder of hoisting equipment and belongs to the technical field of the automatic reverse device for outrigger and oil cylinder. The utility model comprises a sliding bar, a bottom plate, a bent plate and a slide block. The slide block is connected on the bottom plate, the sliding bar is provided with a groove, one end of the bottom plate is inserted into the groove of the sliding bar, one end of the sliding bar is inserted in the slide block, the bent plate is connected with one end of the sliding bar, the other end of the bent plate is connected with a movable leg of the hoisting equipment, the bottom plate is fixed to the outrigger and oil cylinder; the sliding bar through one end of the groove structure pass through bottom plate to form the movable pair; the slide block is fixed on the upper part of the bottom plate with screw after pass through the sliding bar and to form the movable pair of sliding bar on bottom plate with groove of the sliding bar; one end of the bent plate is connected with the end of the sliding bar by pin to form the rotation pair; the other end of the bent plate is connected with the movable leg of the hoisting equipment to form the rotation pair. The turnover device has the advantages of simple structure, esthetic appearance and compact structure; the outrigger oil cylinder of the hoisting equipment can automatically reverse with best driving quality and high working efficiency.
Description
Technical field
The utility model relates to a kind of, particularly a kind of hoisting crane support oil cylinder automatic turning device.
Background technology
At present, the support oil cylinder of lorry-mounted crane does not generally have switching mechanism, all be that support oil cylinder and movable supporting legs are rigidly connected, for the switching mechanism of some middle or small tonnage hoisting crane under the inoperative situation, also be manually support oil cylinder to be overturn 180 ° straight up, or the smaller angle that swings, manual locking pin mechanical interlocking then.
The hoisting crane that support oil cylinder does not have a upset performance is subjected to the influence of car chassis height and influences the popularity of its coupling, simultaneously automobile in the process of moving support oil cylinder easily with obstacle collision, reduction rideability; Particularly under the situation of hoisting crane postposition, the support oil cylinder mechanism that can not overturn has reduced departure angle greatly, has reduced the off-road capability of automobile; Hand turnover mechanism is perhaps arranged, but it wastes time and energy the work efficiency of reduction hoisting crane.
Summary of the invention
The purpose of this utility model be to provide a kind of cross-country, rideability good, the hoisting crane support oil cylinder automatic turning device of high efficiency.
The purpose of this utility model is achieved in that this turning device has sliding bar, base plate, bent plate, slide block, slide block is connected on the base plate, groove is arranged on the sliding bar, one end of base plate is inserted in the groove of sliding bar, one end of sliding bar is inserted in the slide block, bent plate is connected the end of sliding bar, and the other end of bent plate is connected on the movable leg of hoisting crane, and base plate and support oil cylinder are fixed together.
Beneficial effect: owing to adopt such scheme, sliding bar passes base plate by the bathtub construction of an end and forms moving sets; Slide block is passed sliding bar be screwed, form the moving sets of sliding bar on base plate jointly with groove on the sliding bar on base plate top; One end of bent plate forms revolute pair with the end that pin is connected sliding bar; The other end of bent plate is connected on the movable leg of hoisting crane and forms revolute pair, and base plate and support oil cylinder are fixed together, and during work, support oil cylinder is realized spinning upside down automatically by this turning device under deadweight and flexible state; Cross-country, rideability good, high efficiency has reached the purpose of this utility model.This turning device is simple in structure, good looking appearance, and compact conformation, the hoisting crane support oil cylinder can overturn automatically, and is cross-country, rideability good, high efficiency.
Description of drawings
Fig. 1 is a constructional drawing of the present utility model.
Fig. 2 is the side-looking constructional drawing of Fig. 1.
The specific embodiment
Embodiment 1: this turning device has sliding bar 1, base plate 3, bent plate 4, slide block 2, slide block 2 is connected on the base plate 3, on the sliding bar 1 groove is arranged, one end of base plate 3 is inserted in the groove of sliding bar 1, one end of sliding bar 1 is inserted in the slide block 2, bent plate 4 is connected the end of sliding bar 1, and the other end of bent plate 4 is connected on the movable leg of hoisting crane, and base plate 3 is fixed together with support oil cylinder.
Principle of work: bent plate one end of switching mechanism and movable supporting legs constitute revolute pair, and the other end of bent plate constitutes revolute pair with the sliding bar that forms moving sets simultaneously, and base plate then is to be fixed together with support oil cylinder to make circular movement.Steadily flexible by support oil cylinder, thus can be in the deadweight of oil cylinder and the bending moment that under shrinking sliding bar is produced realize up and down steadily upset automatically.
When being turned to vertical state downwards, support oil cylinder stretches out downwards, props hoisting crane.Oil cylinder all has locking pin being fixed on the movable leg of oil cylinder safety at up and down vertical state, at this moment both has been mode of operation and off working state.When oil cylinder upwards reclaims, by compress bending moment that sliding bar produces make oil cylinder upwards upset get back to virgin state.
Claims (1)
1, a kind of hoisting crane support oil cylinder automatic turning device, it is characterized in that: this turning device has sliding bar, base plate, bent plate, slide block, slide block is connected on the base plate, groove is arranged on the sliding bar, one end of base plate is inserted in the groove of sliding bar, and an end of sliding bar is inserted in the slide block, and bent plate is connected the end of sliding bar, the other end of bent plate is connected on the movable leg of hoisting crane, and base plate and support oil cylinder are fixed together.
