Abstract
The utility model discloses a hanging type angling cylinder of a lorry-mounted crane, belongs to the technical field of hoisting, and in particular relates to an angling cylinder of the lorry-mounted crane. The utility model solves the technical problems that: according to the angling cylinder, pistons and a rack piston rod are convenient and labor-saving to assemble, and the pistons are not influenced by a radial force generated in engagement of the rack piston rod. The technical scheme is as follows: a T-shaped hanging column is arranged at a connecting side of each piston and the rack piston rod, U-shaped clamping grooves, which are matched with the T-shaped hanging columns, are arranged on the connecting sides of the both ends of the rack piston rod and the pistons, and both ends of the rack piston rod and the pistons are assorted and hung through the hanging columns and the clamping grooves. The hanging type angling cylinder, provided by the utility model, is widely applied to the field of angling cylinders of the crane.
Description
Technical field
The utility model lorry-mounted crane hanging-connecting angling cylinder belongs to the angling cylinder field, particularly relates to a kind of angling cylinder of lorry-mounted crane.
Background technique
The rotation motion of lorry-mounted crane is to do rotation motion through the rack drives gear shaft of angling cylinder to realize.The rack piston bar of this rotary cylinder is threaded with the general employing of being connected of piston, is unlikely to leak into piston rod one side in order to guarantee fluid, need add seal ring in the cooperation place of piston rod and piston and carry out static seal.Therefore, employing is threaded and has following drawback: 1, the operating cost of static seal height, assembling are wasted time and energy.2, piston is fastenedly connected through screw thread and piston rod, and piston is subject to the radial force in rack piston bar when engagement and causes the directed wearing and tearing of motive sealing between piston and cylinder barrel, and motive sealing reduces working life.
The model utility content
The utility model lorry-mounted crane hanging-connecting angling cylinder has overcome the deficiency that existing technology exists, and provides easy to assembly laborsaving between a kind of piston and the rack piston bar, and the piston angling cylinder that the radial force of generation influences when not receiving the engagement of rack piston bar.
In order to solve the problems of the technologies described above; The technological scheme that the utility model adopts is: lorry-mounted crane hanging-connecting angling cylinder; Comprise cylinder body, piston and rack piston bar; A piston respectively is installed in two cylinder bodies, the two ends of rack piston bar respectively with said two cylinder bodies in piston be connected, said each piston is provided with T shape hanging column with the side that is connected of rack piston bar; Rack piston bar two ends are provided with the U-shaped draw-in groove that adapts with said T shape hanging column with the side that is connected of piston, between the two ends of rack piston bar and the piston through described hanging column with draw-in groove is supporting articulates.
The utility model compared with prior art has following beneficial effect.
The utility model has reached labour-saving easy to assembly purpose between piston and the rack piston bar easily; And owing to adopt the Connecting format that articulates; Between rack piston bar and the piston radially relative displacement can be arranged; Like this, the radial force that the engagement of rack piston bar produces can not pass to piston, guarantees that piston does not receive the influence of radial force.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further explanation.
Fig. 1 is the structural representation of the utility model.
Fig. 2 is a structure of piston schematic representation in the utility model.
Fig. 3 is the side view of the utility model middle rack piston rod.
Embodiment
Like Fig. 1, Fig. 2, shown in Figure 3; The utility model lorry-mounted crane hanging-connecting angling cylinder; Comprise cylinder body 1, piston 2 and rack piston bar 3; A piston 2 respectively is installed in two cylinder bodies 1, and the two ends of rack piston bar 3 are connected with said two cylinder bodies, 1 interior piston 2 respectively, and said each piston 2 is provided with T shape hanging column 4 with the side that is connected of rack piston bar 3; Rack piston bar 3 two ends are provided with the U-shaped draw-in groove 5 that adapts with said T shape hanging column 4 with the side that is connected of piston 2, between the two ends of rack piston bar 3 and the piston 2 through described hanging column 4 and draw-in groove 5 supporting articulating.
The size of draw-in groove 5 wants appropriateness loose with respect to the size of hanging column 4, to guarantee to articulate conveniently; Articulate and to guarantee that the side end face of rack piston bar 3 side end faces and piston 2 can fit after the connection, so that the transmission of pressure.
