Description
Technical field
The utility model relates to a kind of oleo gear that is used for elevator, mainly is installed on elevator hoistways bottom, and is descending or when falling to the hoistway bottom when elevator or counterweight, and it is played the effect of buffering stop.
Background technology
The existing elevator oleo gear of producing both at home and abroad, adopting pressure cylinder, plunger barrel, tapered column, the flow bean choke with annular aperture and switch block mostly is that major part is formed, utilize the impact of the dumping force alleviation of flow of liquid, and utilize spring that it is resetted from car.But the problem that the prior oil pressure energy disperser exists oil hole often to open, when elevator or counterweight acted on the energy disperser, fluid is ejection outwards, thereby needs the running check oil level, can continue after the repairing to use, and caused consumption of fuel very big, and environmental pollution is also bigger.
The utility model content
The purpose of this utility model is to provide a kind of not outwards oil spout, saves oil consumption, and can automatically reset elevator oleo gear.
The utility model elevator oleo gear, comprise the chassis, be welded on the pressure cylinder that is full of fluid on the chassis, plunger barrel with the pressure cylinder free-running fit, be fixed on the taper adjust bar that is positioned at the pressure cylinder center on the chassis, be provided with back-up ring with holes between the top of described pressure cylinder and the plunger barrel, the orienting sleeve of seal ring and felt circle, on the cylindrical of described pressure cylinder top switch block is housed, snap switch is housed on the switch block, on the described plunger barrel compression spring is housed, the lower spring cup that has cutoff port of compression spring is fixedly connected on the upper end of described taper adjust bar, the flow bean choke of ring-type with holes is equipped with in the bottom of plunger barrel, and match with the taper adjust bar, upper spring seat is equipped with in the upper end of compression spring, top at plunger barrel is covered by the fixed connection and sealing of seal ring screw thread, the switch parts that re-pack are housed on the right side of seal cover cap, the re-pack curved slightly contact with snap switch in lower end of parts of described switch is abutted against, cushion rubber is housed on the seal cover cap, the center of seal cover cap has oil hole, and check valve is housed on the oil hole.
The utility model elevator oleo gear, wherein check valve is formed by steel ball (12), compression spring (13), screw plug (14) are housed in the plug screw (11).
The utility model elevator oleo gear wherein is equipped with oil ga(u)ge bar (17) on the chassis.
The utility model elevator oleo gear, because the check valve that adopts plug screw, steel ball, compression spring and screw plug to form, when elevator cage or counterweight act on oleo gear, behind the fluid pressurized, check valve blocks up oil hole, fluid can outwards not sprayed, reduced running check oil level and the constantly work of repairing.The oil ga(u)ge bar is plugged on the chassis, can makes things convenient at any time and take.
Description of drawings
Fig. 1 partly cuts open front view for the utility model elevator oleo gear.
The specific embodiment
Below in conjunction with drawings and Examples in detail the utility model is described in detail.
Elevator oleo gear shown in Figure 1, comprise chassis 31, be welded on the pressure cylinder 22 that is full of fluid on the chassis 31, plunger barrel 16 with pressure cylinder 22 free-running fits, be fixed on the taper adjust bar 26 that is positioned at pressure cylinder 22 centers on the chassis 31, be provided with back-up ring 18 with holes between the top of described pressure cylinder 22 and the plunger barrel 16, the orienting sleeve 4 of seal ring 20 and felt circle 19, on the described pressure cylinder 22 top cylindricals switch block 1 is housed, snap switch 27 is housed on the switch block 1, compression spring 5 is equipped with in described plunger barrel 16 inside, the lower spring cup that has cutoff port 23 of compression spring 5 is fixedly connected on the upper end of described taper adjust bar 26, the flow bean choke 2 of ring-type with holes is equipped with in the bottom of plunger barrel 16, and match with taper adjust bar 26, upper spring seat 9 is equipped with in the upper end of compression spring 5, top at plunger barrel 16 covers 6 by seal ring 7 screw thread fixed connection and sealing, the switch parts 15 that re-pack are housed on the right side of seal cover cap 6, the re-pack curved slightly contact with snap switch 27 in lower end of parts 15 of described switch is abutted against, cushion rubber 8 is housed on the seal cover cap 6, and the center of seal cover cap 6 has oil hole.Described oil hole is threaded, and plug screw 11 is threaded with described oil hole by seal ring 10, and steel ball 12, compression spring 13, screw plug 14 composition check valves are housed in the plug screw 11.
Descending or when falling when elevator or counterweight to the hoistway bottom, cushion at collision plunger barrel (16) compressing makes it descending, under the effect of the lower spring cup (23) on the taper adjust bar (26), compression spring (5) in the compression plunger tube (16), hydraulic oil in the while compressed pressure cylinder (22), fluid enters plunger barrel (16) inside by the gap between the flow bean choke (2) of taper adjust bar (26) and plunger barrel (16) bottom, along with plunger barrel (16) is descending, the diameter of taper adjust bar (26) becomes big gradually, make flow bean choke (2) more and more littler with the gap of taper adjust bar (26), hydraulic oil in the pressure cylinder (22) is compressed, internal pressure is more and more higher, add the sealing of closed check valve and each seal ring, make pressure cylinder (22) and plunger barrel (16) form confined space, making plunger barrel (16) be subjected to resistance in descending process increases gradually, and descending slowing down gradually until stopping to be realized the buffering stop effect of energy disperser to lift car or counterweight.To drive the switch parts (15) that re-pack descending along with plunger barrel (16) moves down, and the contact of snap switch (27) is closed to the right gradually, and the towing machine outage is shut down.
When lift car or counterweight left energy disperser, plunger barrel (16) began to reset under the effect of compression spring (5) and makes it up, and the contact automatic or manual of snap switch (27) resets, and made the elevator traction machine energising, and elevator normally moves.
