Abstract
The utility model discloses a box type telescopic boom comprising a telescopic boom cylinder (1), a slider device is arranged on the telescopic boom cylinder (1) and comprises a limiting device (2) arranged on the telescopic boom cylinder (1), and a slider with a groove, and one end of the slider (3) with the groove is arranged in the limiting device (2). As for the box type telescopic boom with the structure, a box of the traditional box type telescopic boom for containing a head slider of the telescopic boom is improved to be the slider device, so that the structure of the box type telescopic boom is simplified, the whole weight is lightened, the whole operation performance is improved, and the total extended length and operation range of the telescopic boom are increased; and simultaneously, the box type telescopic boom can solve the problems of force transmission and excessively extensive stress effectively by increasing the length of the slider device, is convenient to manufacture, disassemble, assemble and maintain, thus further improving production efficiency.
Description
Technical field
The utility model relates to a kind of box-shaped telescopic boom.
Background technology
Traditional box-shaped telescopic boom normally is provided with casing in addition on telescopic boom, in order to place the head slide block of telescopic boom, this box-shaped telescopic boom is owing to set up casing, therefore its longitudinal size is big, this not only can increase the weight of whole telescopic boom, and complex structure, manufacturing cost is higher, more is unfavorable for solving the problem of stress concentration; Further be, this box-shaped telescopic boom also is not easy to dismounting and maintenance, and production efficiency is on the low side.
The utility model content
At above-mentioned deficiency, the utility model provides a kind of not only longitudinal size little, simple in structure, and can effectively solve the box-shaped telescopic boom of problem of stress concentration.
The utility model is to realize by such technical scheme:
A kind of box-shaped telescopic boom comprises the telescopic boom cylindrical shell, and described telescopic boom cylindrical shell is provided with slide block device.
Described slide block device comprises inhibiting device and the trough of belt slide block that is arranged on the described telescopic boom cylindrical shell, and an end of this trough of belt slide block is placed in the described inhibiting device.
Described inhibiting device is a U type groove baffle plate, and an end of described trough of belt slide block is positioned in the U type groove of this U type groove baffle plate, to carry out spacing to described trough of belt slide block.
In order to prevent that described inhibiting device from coming off in the course of the work, described inhibiting device is good on the described telescopic boom cylindrical shell to be fixedly welded on, as the case may be other similar connection modes.
The cephalic par of this box-shaped telescopic boom is provided with the end baffle of the other end that blocks described trough of belt slide block.
For convenience to the Assembly ﹠Disassembly of above-mentioned slide block device, described end baffle is fixed in the cephalic par of box-shaped telescopic boom by bolt and nut, perhaps also can be fixing flexibly by other modes.
Owing to adopted said structure, the beneficial effects of the utility model are as follows:
The utility model provides a kind of later-model box-shaped telescopic boom, this box-shaped telescopic boom is provided with slide block device, comprise inhibiting device and trough of belt slide block etc., and this trough of belt slide block is directly installed in the telescopic boom cylindrical shell, thereby the head construction of telescopic boom can directly be sleeved on outside the telescopic boom cylindrical shell, to reduce the longitudinal size of telescopic boom head; Traditional box-shaped telescopic boom is slide block device in order to the casing improvement of placing telescopic boom head slide block, not only simplified the structure of telescopic boom, reduce its overall weight, improved the transaction capabilities of car load, but also increased the full elongation and the scope of work of telescopic boom; Simultaneously, this box-shaped telescopic boom can come the problem that effective improvement power is transmitted and stress is too concentrated by the length that increases slide block device, be convenient to make produce, the dismounting maintenance, thereby further enhance productivity.
Description of drawings
Fig. 1 is the constructional drawing of box-shaped telescopic boom among the utility model embodiment.
The specific embodiment
In order to be expressly understood the purpose of this utility model, technical scheme and beneficial effect more, below in conjunction with accompanying drawing the utility model is described further, but protection domain of the present utility model is not limited in following examples.
As shown in Figure 1, a kind of box-shaped telescopic boom comprises telescopic boom cylindrical shell 1, and described telescopic boom cylindrical shell 1 is provided with slide block device; Described slide block device comprises inhibiting device 2 and the trough of belt slide block 3 that is arranged on the described telescopic boom cylindrical shell 1, and an end of this trough of belt slide block 3 is placed in the described inhibiting device 2; Described inhibiting device 2 is a U type groove baffle plate, and an end of described trough of belt slide block 3 is positioned in the U type groove of this U type groove baffle plate; Described inhibiting device 2 is fixedly welded on the described telescopic boom cylindrical shell 1; The cephalic par 4 of this box-shaped telescopic boom is provided with the end baffle 5 of the other end that blocks described trough of belt slide block 3; Described end baffle 5 is fixed in the cephalic par 4 of box-shaped telescopic boom by bolt and nut 6.
