The specific embodiment
Be elaborated below in conjunction with the specific embodiment of accompanying drawing to the utility model.Should be understood that the specific embodiment described herein only is used for explanation and explains the utility model, is not limited to the utility model.
In the utility model, do not doing under the situation of opposite explanation, " preceding " is meant the direction of arrow indication among Fig. 1 to Fig. 3, " back " is meant and said " preceding " opposite direction.
An aspect as the utility model; As shown in Figures 2 and 3, the utility model provide a kind of telescopic hoist boom to flushing device, said telescopic hoist boom comprises at least two joint arms joints 10; Between the said arm head 11 that flushing device is arranged on adjacent two joint arms joints 10; Wherein, on the back surface of the arm head 11 of last joint arm joint 10, be formed with or be fixed with the piece 22 that liquidates, on the front surface of the arm head 11 of back one joint arm joint 10, be fixed with the piece 22 or be provided with of liquidating jet-bedding 20 to jet-bedding 20; This is to being provided with elastomer block 21 in the jet-bedding 20, the piece 22 that liquidates is provided with contact resilient piece 21 with jet-bedding 20 is aimed at.
Shown in Fig. 2 is a kind of embodiment of the utility model; The arm head 11 of last joint arm joint 10 is provided with jet-bedding 20; Be fixed with the piece 22 that liquidates on the arm head 11 of back one joint arm joint 10; When telescopic hoist boom bounced back, last joint arm saved one joint arm joint, the 10 retraction playback towards the back of the direction in the opposite direction shown in the arrow among 10 edges and Fig. 2.When the arm head 11 of last joint arm joint 10 near the arm head 11 of back one joint arm joint 10 to a certain degree the time, the piece 22 that liquidates on the one joint arm joint 10 of back insert on the last joint arm joint 10 to jet-bedding 20.Along with the continuation retraction of telescopic hoist boom, the elastomer block 21 to jet-bedding 20 of liquidate piece 22 and last joint arm joint 10 on the one joint arm joint 10 of back.21 pairs of bumps of elastomer block cushion, thereby have avoided the hard collision between the adjacent two joint arms joints, have reduced in the process that liquidates arm head 11 and damage that flushing device is caused.
Likewise; To be arranged on the front surface of arm head 11 of back one joint arm joint 10 jet-bedding 20; The piece 22 that liquidates is fixed on the back surface of arm head 11 of last joint arm joint 10 and can realizes having avoided the hard collision between the adjacent two joint arms joints equally; Reduced in the process that liquidates the purpose of the damage that causes to arm head 11 and to flushing device, its principle is identical with the embodiment shown in Fig. 2, repeats no more here.
In the utility model, the material of elastomer block 21 there is not specific (special) requirements, as long as can in the process that liquidates, cushion the impulsive force that the piece 22 that liquidates produces.For example, elastomer block 21 can be processed by the rubber elastomeric material, also can be processed by the spring plate that is provided with spring.
Usually, liquidate piece 22 through the welding mode be fixedly installed on the front surface of arm head 11.Certainly, the piece 22 that liquidates also can be fixed on the front surface of arm head 11 through attaching parts.Can be formed directly into jet-bedding on the back surface of arm head 11.For the ease of setting to flushing device, especially to the setting of the elastomer block in the flushing device 21, preferably, said to flushing device can comprise captive joint with arm head 11 to red seat 23, jet-bedding 20 is formed in the red seat 23.Certainly, elastomer block 21 also is arranged in the red seat.

Preferably, as shown in Figure 4, saidly can comprise regulating block 25 to flushing device, this regulating block 25 is arranged between moving housing 23a and the longitudinal ligament plate 12.Can move housing 23a in the position of fore-and-aft direction along the thickness adjustment of fore-and-aft direction through changing regulating block 25, and then adjustment is to the position of jet-bedding 20 at fore-and-aft direction.
Preferably, can be connected with cross-tie plate 13 between longitudinal ligament plate 12 and the front flange 11a, so that longitudinal ligament plate 12 is supported.
In order to regulate moving housing 23a along the vertical direction and should to move the position among the housing 23a to jet-bedding 20; Preferably; Said flushing device is comprised adjusting screw(rod) 26; The upper surface of fixed shell 23b and/or lower surface are provided with the tapped bore 26a that matches with adjusting screw(rod) 26, and an end of adjusting screw(rod) 26 passes fixed shell 23b with the upper-lower position of adjustment to jet-bedding 20.As shown in Figure 3, adjusting screw(rod) 26 end face is against on the guide 24.
Preferably, all be provided with tapped bore 26a on the upper surface of fixed shell 23b and the lower surface.Turn adjusting screw(rod) 26 that passes the upper surface and the adjusting screw(rod) 26 that passes the lower surface simultaneously; Adjusting screw(rod) 26 that passes on the end face and the adjusting screw(rod) 26 that passes on the end face are moved down simultaneously; Guide 24, elastomer block 21 among housing 23a and the moving housing 23a are moved down; Thereby adjustment is to the position of jet-bedding 20, and vice versa.
Should be understood that; When install adjustment screw rod 26; Can be on the upper and lower end face of moving housing 23a, through hole be set, but makes the end face of adjusting screw(rod) 26 directly be against on the upper and lower end face of moving housing 23a, and the regulative mode of adjusting screw(rod) identical with described in the preceding text.
Usually, telescopic hoist boom can comprise single oil cylinder joint 10 (that is, telescopic hoist boom comprises that two joints or two joints are with upper arm joint 10).It is described to flushing device between two adjacent arbitrarily joint arm joints 10, the utility model to be set.
Another aspect as the utility model also provides a kind of hoisting crane, and this hoisting crane comprises telescopic hoist boom, and wherein, it is above-mentioned to flushing device that said telescopic hoist boom comprises that the utility model provides.Have above-mentioned hoisting crane to flushing device when telescopic hoist boom shrinks, the head-on collision of alternate arm joint is by buffering effectively, thus the service life of having improved telescopic hoist boom.
In the utility model, through in to flushing device, being provided with, and elastomer block is set in to jet-bedding at this to jet-bedding, make that elastomer block can cushion the process of liquidating when telescopic hoist boom shrank.
More than combine accompanying drawing to describe the preferred implementation of the utility model in detail; But; The utility model is not limited to the detail in the above-mentioned embodiment; In the technical conceive scope of the utility model, can carry out multiple simple variant to the technical scheme of the utility model, these simple variant all belong to the protection domain of the utility model.
Need to prove that in addition each the concrete technical characterictic described in the above-mentioned specific embodiment under reconcilable situation, can make up through any suitable manner.For fear of unnecessary repetition, the utility model is to the explanation no longer separately of various possible array modes.
In addition, also can carry out combination in any between the various embodiment of the utility model, as long as its thought without prejudice to the utility model, it should be regarded as content disclosed in the utility model equally.
