Abstract
The utility model provides a telescopic thick well rolling locking cylinder pressure measuring device, includes: a screw hole for hoisting, an oil groove, an oil pipe joint and a locking cylinder barrel; the oil pipe joint is fixed at the middle lower part of the locking cylinder barrel; the oil pipe joint is communicated with an oil groove formed in the locking cylinder barrel; 4 hoisting screw holes are uniformly distributed on the upper surface of the locking cylinder barrel; the locking cylinder barrel is connected with the piston, the disc spring, the sealing element and the like in a matching way; the oil groove is connected with the sealing element in a matching way; 4 oil holes are uniformly distributed on the circumference of the outer side of the locking cylinder barrel; the 4 oil holes are communicated with the oil groove; the oil pipe joints are matched and connected with oil holes formed in the oil groove of the locking cylinder barrel. The advantages are that: the locking cylinder is completely simulated in the in-use state. Whether the locking cylinder acts normally can be effectively tested. The locking cylinder body can not be used for tapping to cause abnormal actions of the locking cylinder after being mounted on the machine, so that the pressure test device is different from a field use state, the test effect cannot be completely equivalent to the field use state, and the like. The device has simple structure, and is practical and reliable.
Description
The technical field is as follows:
the utility model relates to a steel rolling auxiliary assembly technical field especially relates to a telescopic thick well rolling locking cylinder pressure measurement device.
Background art:
in the prior art, the locking cylinder pressure measuring device is connected with a hydraulic oil distribution block through an oil supply pipe by using a small hydraulic station, and the distribution block is divided into 4 oil pipes which are connected with 4 oil holes in the locking cylinder to perform a pressure test. The disadvantages and drawbacks of this device are: the locking cylinder is tapped, so that the locking cylinder acts abnormally after being mounted on a machine. The method mainly comprises the steps that the original pressure testing device is different from the field use state, and the testing effect cannot be completely equivalent to the field use state.
The utility model has the following contents:
the utility model aims at overcoming the not enough of prior art, providing a can simulate the locking cylinder completely and roll locking cylinder pressure measurement device in machine user state in thick well, whether can test the locking cylinder action normal effectively.
The utility model discloses a solve the technical scheme that above-mentioned problem provided and be: a telescopic thick and medium rolling locking cylinder pressure measuring device is characterized by comprising: a screw hole for hoisting, an oil groove, an oil pipe joint and a locking cylinder barrel; the oil pipe joint is fixed at the middle lower part of the locking cylinder barrel; the oil pipe joint is communicated with an oil groove formed in the locking cylinder barrel; 4 hoisting screw holes are uniformly distributed on the upper surface of the locking cylinder barrel; the locking cylinder barrel is connected with the piston, the disc spring, the sealing element and the like in a matching way; the oil groove is connected with the sealing element in a matching way; 4 oil holes are uniformly distributed on the circumference of the outer side of the locking cylinder barrel; the 4 oil holes are communicated with the oil groove; the oil pipe joints are matched and connected with oil holes formed in the oil groove of the locking cylinder barrel. It is also characterized in that: the locking cylinder barrel is processed by selecting a thick-wall steel pipe. An O-shaped sealing ring is selected as a sealing element for matching connection in an oil groove on the locking cylinder body.
The utility model has the advantages that: the locking cylinder on-machine use state is completely simulated, whether the locking cylinder acts normally can be effectively tested, and the problems that the locking cylinder acts abnormally after being on-machine due to tapping of the locking cylinder body, a pressure testing device is different from the on-site use state, the testing effect cannot be completely equivalent to the on-site use state and the like can be solved. The device has simple structure, and is practical and reliable.
Description of the drawings:
fig. 1 is a structural diagram of a sleeve type pressure measuring device of a locking cylinder for rough and medium rolling in the embodiment of the invention.
In the drawings: 1. a screw hole; 2. an oil sump; 3. an oil pipe joint; 4. and locking the cylinder barrel.
The specific implementation mode is as follows:
the invention will be described in further detail with reference to the accompanying drawings and embodiments, wherein a sleeve type pressure measuring device for a rough and medium rolling locking cylinder, as shown in fig. 1, comprises: the device comprises a screw hole 1 for hoisting, an oil groove 2, an oil pipe joint 3 and a locking cylinder barrel 4; the oil pipe joint 3 is fixed at the middle lower part of the locking cylinder barrel 4, and the oil pipe joint 3 is communicated with an oil groove 2 formed on the locking cylinder barrel 4; 4 hoisting screw holes 1 are uniformly distributed on the upper surface of the locking cylinder barrel 4; the locking cylinder barrel 4 is connected with a piston, a disc spring, a sealing element and the like in a matching way; the oil groove 2 is connected with a sealing element in a matching way; 4 oil holes are uniformly distributed on the circumference of the outer side of the locking cylinder barrel 4; the 4 oil holes are communicated with the oil groove 2; the oil pipe joint 3 is connected with an oil hole formed on the oil groove 2 of the locking cylinder barrel 4 in a matching way. The locking cylinder barrel is processed by selecting a thick-wall steel pipe, and an O-shaped ring on the locking cylinder body is used as a sealing element.
The utility model discloses a theory of operation is: the locking cylinder mainly comprises a locking cylinder barrel 4, a piston, a disc spring and a sealing element which are connected in a matched mode. Under the non-pressing state and under the action of the disc spring, the piston cylinder head is in an extending state; in the pressing state, the piston cylinder head is in a retracting state. 4 oilholes of evenly distributed all around in the 4 outsides of locking cylinder, in order to reach test effect, must guarantee to supply oil simultaneously through these 4 oilholes and suppress or return the oil pressure release.
