Abstract

The utility model discloses an energy accumulator fixing device, and belongs to the technical field of engineering machinery. The energy accumulator fixing device comprises a balance weight used for the engineering machinery, an energy accumulator, a hoop and a bottom support. A groove matched with the energy accumulator is arranged in the surface of the balance weight, and the energy accumulator is arranged inside the groove and fixed with the bottom support through the hoop. By arranging the groove in the balance weight and arranging the energy accumulator in the groove of the balance weight, limited space inside a machine is utilized effectively, the energy accumulator is protected well, and the energy accumulator is prevented from being collided.

Description

A kind of accumulator fastening devices

Technical field

The utility model relates to technical field of engineering machinery, particularly a kind of accumulator fastening devices for engineering machinery.

Background technology

Accumulator is a kind of energy savings device in the hydropneumatic system.It is in due course and changes the energy in the system into compression energy or potential energy stores, and when system needs, again compression energy or potential energy is changed into the energy such as hydraulic pressure or air pressure and discharges, and again mends feed system; When system's instantaneous pressure increased, it can absorb the energy of this part, guaranteed that whole system pressure is normal.Accumulator is fixed on the acting body by hard-wired mode and plays a role.

Present accumulator generally is by bottom bracket 3 and rubber pad 2 load-bearing, and the middle mode that adopts anchor ear 1 to fix is fixed in the acting body surface with accumulator 4, as shown in Figure 1.But this mode is fixing; for the engineering machinery such as excavator, can not effectively utilize bulk, the accumulator slightly large for specification can only be fixed on the machine external space; can not effectively protect accumulator like this, the potential danger that also can exist some collisions to cause simultaneously.

The utility model content

Can not effectively utilize bulk, accumulator to be fixed on the machine external space for the fastening devices that solves present accumulator and be unfavorable for protecting accumulator, have the problem of the danger of collision, the utility model provides a kind of accumulator fastening devices.Described technical scheme is as follows:

A kind of accumulator fastening devices, comprise balance weight body, accumulator, anchor ear and bottom bracket that engineering machinery is used, wherein, described balance weight body surface is provided with the groove that matches with described accumulator, described accumulator is installed in the described groove, and fixes by described anchor ear and described bottom bracket.

Preferably, described balance weight body surface is provided with the semi-cylindrical recesses that described accumulator is installed and the square groove that hydraulic part is installed.

Preferably, described balance weight body is provided with the stone bolt for fixing described anchor ear and described bottom bracket.

Preferably, described anchor ear has 2 at least.

Preferably, also be provided with rubber pad between described bottom bracket and the described accumulator.

Compared with prior art; the accumulator fastening devices that technique scheme provides has the following advantages: by being provided with groove in balance weight body; accumulator is installed in the groove of balance weight body; both effectively utilized the limited bulk of machine intimate; the good accumulator of having protected is arranged, prevented the generation of accumulator collision.

Description of drawings

In order to be illustrated more clearly in the technical scheme among the utility model embodiment, the accompanying drawing of required use was done to introduce simply during the below will describe embodiment, apparently, accompanying drawing in the following describes only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.

The specific embodiment

For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing the utility model embodiment is described in further detail.

Extremely shown in Figure 4 such as Fig. 2, the utility model embodiment provides a kind of accumulator fastening devices, comprise balance weight body 5, accumulator 4, anchor ear 1 and bottom bracket 3 that engineering machinery is used, balance weight body 5 surfaces are provided with the semicolumn groove that matches with accumulator 4, accumulator 4 is installed in this groove, take full advantage of limited bulk, and by the fixing accumulator 4 of anchor ear 1 and bottom bracket 3.Wherein balance weight body 5 is inner fills with that filler, surface design are arranged is that the first half is cylinder shape groove, carries out correspondingly with the column structure of accumulator 4, and the bottom is the square groove structure, is used for the installation of supporting hydraulic part.Bottom bracket 3 and anchor ear 1 are and balance weight body 5 and accumulator 4 structure matching, with abundant fixedly accumulator 4.Balance weight body 5 is provided with a plurality of stone bolt 6, is used for solid bottom support 3 and anchor ear 1, and stone bolt 6 roots are embedded in balance weight body 5 fillers the inside, strengthens the intensity of whole bottom bracket 3.When mounted, 2-3 anchor ear 1 be accumulator 4 fixedly, uses nut that anchor ear 1 is fixed on the stone bolt 6.Also be provided with rubber pad 2 between bottom bracket 3 and the accumulator 4, rubber pad 2 and bottom bracket 3 be load-bearing accumulator 4 together, and by nut bottom bracket 3 is fixed on the stone bolt 6.

The disclosed accumulator fastening devices of the utility model embodiment is installed in accumulator in the semicolumn groove on balance weight body surface, has effectively utilized the limited bulk in mechanical inside; Accumulator is installed on the inner space, has obtained better protection, can rainproof anti-collision; The groove on balance weight body surface is convenient to the installation and maintenance of accumulator, and the square groove structure is convenient to the installation and maintenance of hydraulic part.

The above only is preferred embodiment of the present utility model, and is in order to limit the utility model, not all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
