The invention relates to a hydraulic shock absorber. A piston (24) connected with a piston rod (27) is fitted in a cylinder (3) having a hydraulic fluid sealed therein. A damping force is generated through extension (31) and compression disk valves (32) and an orifice (33). Vehicle height adjustment is performed with a self-leveling mechanism (S) by transferring the hydraulic fluid between the cylinder and a hydraulic fluid tank (10). A bladder (12) of the hydraulic fluid tank (10) is clamped between an outer flange portion (9) of a partition member (8) and a casing (2). Because the hydraulicfluid tank is formed without welding, it is possible to avoid contamination of the hydraulic fluid by welding sputter and thermal deformation. Provision of an O-ring (49) on the outer flange portion can reduce the pressure acting from a reservoir (11) on the clamped portion of the bladder (12) and hence prevent dislodging of the bladder.

The invention provides a mechanical connection conducting cooling type semiconductor laser unit stack packaging structure which is used for improving the reliability of a product and prolonging the service life of the product. On an insulation structure, a laser unit stack is located in the middle, a positive electrode connecting block and a negative electrode connecting block are located on the two sides of the laser unit stack, the positive electrode connecting block and the negative electrode connecting block are fixedly connected with a basic heat sink in the mode that fastening screws obliquely penetrate through the insulation structure downwards, the opposite inner side faces of the positive electrode connecting block and the negative electrode connecting block are both slopes, the two slopes are closed downwards overall, and the outer side faces at the two ends of the whole laser unit stack are also slopes which are matched with the two slopes respectively, so that under the screwing effect of the fastening screws arranged obliquely downwards, all chip modules are pressed to the middle and downwards through the positive electrode connecting block and the negative electrode connecting block, and therefore the mechanical connection conducting cooling type semiconductor laser unit stack packaging structure is finally acquired.

The invention relates to the technical field of compressors, in particular to an assembling method for a liquid storage device and a compressor. The assembling method comprises the steps that a through hole is formed in a side surface of a housing; a flange is formed at the edge of the through hole; the diameter of the through hole is greater than the outer diameter of an air inlet pipe; an air cylinder is placed in the housing; a first end of the air inlet pipe penetrates the through hole and is pressed into an air inlet of the air cylinder; a seal groove is formed at the air inlet and internally provided with a seal ring; the seal ring is connected with a side wall of the air inlet pipe in a sleeving manner; and the flange is welded with the air inlet pipe along the excircle of the air inlet pipe after the air cylinder is fixed in the housing. According to the assembling method, the air inlet pipe is connected with the housing directly, refrigerant gas enters the air cylinder directly through the air inlet pipe and passes through few parts; and the seal ring is arranged between the air inlet pipe and the air inlet of the air cylinder, so that leakage is avoided. As the air inlet pipe is fixed by the flange, the structure is simple; the assembling is convenient; welding positions are few; the welding material consumption and the labor intensity can be reduced; and the production efficiency can be improved.

The invention provides a crawler frame, which is formed by a center frame and left and right track frames extending forward and backward on the left and right sides of the center frame, and is made of cast steel castings to connect the center frame part of the center frame and the track frame. Outriggers, the structure of the outriggers connecting the center frame of the track frame makes the soil rarely adhere to and accumulate, so it is easy to clean and simple to manufacture.

The invention discloses a conveniently overhauled crane carriage for a crane. A movable maintenance platform is arranged on the crane carriage. A crane carriage frame comprises two walking beams and a bearing beam which are arranged in an I shape. The two ends of each winding drum are arranged on two winding drum fixing bases respectively. A dedicated monitoring device comprises an installing frame composed of two fixed segments and a horizontal segment. A driving chain wheel, a driven chain wheel and a chain are arranged in the horizontal segment, a horizontal mobile platform is fixed to the chain, and a rotary mobile platform is rotationally connected to the horizontal mobile platform. According to the conveniently overhauled crane carriage for the crane, the crane carriage can be produced through a modularized assembling mode and has the advantages of being simple in structure, few in welding point and light in self weight, welding portions can be decreased effectively at the same time, and the situation that the errors of crane carriage wheel lines are too large due to welding deformation is avoided; in addition, whether the surface of a main beam has deformation or cracks or the working conditions of driving wheels and driven wheels can be monitored in real time through a camera, and meanwhile the overhauling efficiency is improved.
