[0004] However, there are usually two guide rails arranged parallel to each other in the existing rail transit routes. For practitioners in the gauge adjustment industry, the hydraulic gauge adjuster with the above-mentioned structure can only adjust a single rail gauge therein. In fact, the best way to adjust the track gauge is to set the center between the two guide rails, and push the guide rails to both sides at the same time to realize the positioning and adjustment of the guide rails on both sides. Hydraulic gauge adjuster for distance between guide rails

Embodiment Construction
[0030] The following combination Figure 1-Figure 6 The present invention is described in further detail.
[0031] A gauge adjuster, comprising a vortex linear propulsion seat 1 with a hollow interior, the inner hollow part of the propulsion seat 1 is a vortex linear hydraulic chamber 16, and the two ends of the propulsion seat 1 are respectively useful At the oil port 2 that is connected to the external hydraulic power source 18 and communicates with the inside of the hydraulic chamber 16, the material of the propulsion seat 1 is plastic;
[0032] The hydraulic chamber 16 is sealed and slidably connected with a propelling plug 3. The moving path of the propelling plug 3 in the hydraulic chamber 16 is a vortex linear shape. The propelling plug 3 is made of metal, and the material of the propelling plug 3 can be iron; wherein The outer walls around the push plug 3 made of metal can be wrapped with a rubber layer (not shown in the figure). It is also conducive to the smooth sl...

The invention discloses a rail distance adjuster. According to the technical scheme, the rail distance adjuster comprises a propulsion base in a spiral shape, and the propulsion base is hollow. The interior hollow portion of the propulsion base is a hydraulic cavity in a spiral shape. The two ends of the propulsion base are each provided with an oil through end which is used for being connected with an external hydraulic power source and communicates with the interior of the hydraulic cavity. The propulsion base is made of plastic. A propulsion plug is slidably connected in the hydraulic cavity in a sealed mode, the motion path of the propulsion plug in the hydraulic cavity is in a spiral shape, and the propulsion plug is made of metal. A propulsion block is slidably connected to the propulsion base. An electromagnet used for being attracted with the propulsion plug is arranged in the propulsion block, and the electromagnet is connected with an external power supply. The propulsion block is provided with a contact part capable of making contact with the outer side wall of a guide rail. A fixing part used for being fixed to the ground is connected to the middle position of the propulsion base. Through the technical scheme, the purpose of adjusting the distance between two adjacent guide rails at a time can be achieved.
Description
technical field [0001] The invention relates to a position adjustment device, in particular to a gauge adjuster. Background technique [0002] With the speed-up of domestic railway passenger trains and the construction of high-speed passenger dedicated lines, the allowable deviations of the railway line gauge acceptance standards have been stipulated accordingly, and the deviation values have been greatly reduced. Technical requirements, gauge adjustment is one of the operations involved in daily maintenance and repair of public works. [0003] Existing hydraulic gauge gauge such as the Chinese patent application number 200920304411.4 is a manual hydraulic gauge adjuster suitable for Pandrol fastener sleepers, including a base, a plunger pump and an oil tank located on the base, and a There is a plunger oil cylinder, and a plunger protruding from the outside of the plunger oil cylinder is provided. The plunger oil cylinder and the plunger pump are connected through the oi...
