Abstract
The utility model discloses a hydraulic manual pump for lifting a truck cab. The pump comprises an oil tank and a pump body, wherein the pump body is provided with a left oil outlet pipe joint and a right oil outlet pipe joint; a reversing valve is arranged in the pump body; a plunger is arranged in the oil tank; the front end of the plunger stretches into the pump body and is provided with a one-way valve; a suction valve of the one-way valve is communicated with an inner cavity of the oil tank; a discharge valve of the one-way valve is communicated with the reversing valve; a large spring is sleeved outside the plunger; the top of the large spring is pressed against a spring seat fixed on the top of the plunger; a swing handle is rotatably arranged on the upper part of the oil tank and is connected with a rotating wheel pressed on the spring seat; and a boosting rod socket is fixedly connected with the external part of the swing handle. The pump has high volumetric efficiency, small leakage, uniform flow and low noise, can works under high pressure, is mostly used for a high-power hydraulic system, and is stably operated.
Description
Technical field
The utility model relates to oil hydraulic pump, specifically belongs to a kind of truck cap lifting hydraulic manual pump.
Background technique
Oil hydraulic pump is a kind of hydraulic element that pressurized liquid is provided for hydraulic transmission, is a kind of of pump.Its function is the pressure energy that the mechanical energy of power engine (as motor and internal-combustion engine etc.) is converted to liquid.Output flow can be regulated as required is called variable displacement pump, and flow can not be regulated is called metering pump.Pump commonly used has 3 kinds of gear pump, vane pump and plunger pumps in the hydraulic system.Gear pump: volume is less, and structure is simpler, and not tight to the turbidity test requirement of oil, price is more cheap; But pump shaft is subjected to unbalanced force, and serious wear is leaked bigger.Vane pump: be divided into double-acting vane pump and single acting vane pump.
The model utility content
The purpose of this utility model has provided a kind of truck cap lifting hydraulic manual pump, and the volumetric efficiency height leaks for a short time, can under high pressure work, and uses the what high-power hydraulic system mostly, and pump duty is even, running steadily, noise is little.
The technical solution adopted in the utility model is as follows:
Truck cap lifting hydraulic manual pump, include fuel tank, the pump housing, the pump housing is provided with left flowline connection to subsea, right flowline connection to subsea, be provided with selector valve in the pump housing, be provided with plunger in the fuel tank, the front end of plunger extend in the pump housing, the front end of plunger is equipped with one-way valve, the suction valve of one-way valve communicates with the fuel tank inner chamber, and the expulsion valve of one-way valve communicates with selector valve, and the outlet of selector valve communicates corresponding to left flowline connection to subsea, right flowline connection to subsea; Plunger is set with big spring outward, and the top overhead of big spring is on the spring seat that is fixed in plunger top, and the top of fuel tank is rotated and is provided with the pendulum handle, and the pendulum handle is connecting the runner that is pressed on the spring seat, and pendulum handle outer fixing is connected with the extension lever socket.
Plugged together extension lever in the described extension lever socket.
Be fixed with handle on the described selector valve outer radial.
The utility model inserts the extension lever socket with extension lever, the extension lever socket is rotated by the spline handle, driving the pendulum handle simultaneously rotates, the rotation of pendulum handle moves downward contacted with it spring seat and plunger rod together, the spring seat that moves downward compresses big spring, when the end face of spring seat touched the end face of plunger case, spring seat and plunger rod stopped to move downward, and spring stops to shrink.
Extension lever is inserted the extension lever socket, drive the spline handle and rotate, drive the pendulum handle by the spline on the spline handle and rotate, the rotation of pendulum handle moves downward contacted with it spring seat and plunger rod together, and the spring seat that moves downward compresses big spring; When the end face of spring seat touched the end face of plunger case, spring seat and plunger rod stopped to move downward, and spring stops to shrink.Compressed big spring is because the elastic force of self rise automatically, the drive spring seat moves upward, the moving upward of spring seat drives plunger rod simultaneously and moves upward together, when the extension lever socket is got back to initial position, continue hand extension lever, repeat above motion, just can realize that plunger rod constantly slides up and down in plunger case.
Reversing handle is placed the position, extension lever inserts the extension lever socket, hand extension lever between position and position, driving plunger rod slides up and down in plunger case, constantly hydraulic oil is sucked in the plunger case from the suction valve of fuel tank through one-way valve, by the expulsion valve of one-way valve, discharge again from oil connection, provide high pressure oil to system, the hydraulic oil in the system is through the oil connection oil sump tank.Extension lever inserts the extension lever socket, driving plunger rod slides up and down in plunger case, constantly hydraulic oil is sucked in the plunger case from the suction valve of fuel tank through one-way valve, expulsion valve by one-way valve again, discharge from oil connection, provide high pressure oil to system, the hydraulic oil in the system is through the oil connection oil sump tank.
Compared with the prior art, the beneficial effects of the utility model are as follows:
Volumetric efficiency height of the present utility model leaks for a short time, can under high pressure work, and uses the what high-power hydraulic system mostly, and pump duty is even, running steadily, noise is little.
