Problems solved by technology
[0003] The object of the present invention is to provide a rock drilling jumbo propulsion oil cylinder ejector device to solve the problem that the existing oil cylinder jack device in the above background technology is not convenient to adjust the length of the ejector rod according to the situation of use, which makes the operation inconvenient. During permanent operation, the middle position of the ejector rod is in a suspended state, which makes the operation of the ejector rod unstable and affects the operation effect. It is not convenient to protect the end after operation, which makes the end easily deformed.

The invention discloses a rock drilling trolley propelling oil cylinder ejector rod device. The rock drilling trolley propelling oil cylinder ejector rod device comprises a propeller, a second ejectorrod is mounted on the upper surface of the propeller, one end of the second ejector rod is welded and fixed to a fixing rod, the inner part of the fixing rod is clamped and fixed to a bearing, the end part of the second ejector rod is rotationally connected with a connecting rod through the bearing, the end part of the connecting rod is fixedly connected with a hand wheel, one side of the hand wheel is fixedly connected with a threaded rod, and the end part of the threaded rod is rotationally connected with a first ejector rod at one end of the upper surface of the propeller. According to therock drilling trolley propelling oil cylinder ejector rod device, the connecting rod is designed at one end of the hand wheel and the threaded rod is designed at the other end of the hand wheel, so that the length of the ejector rod is not convenient to adjust according to the use condition of the oil cylinder ejector rod device, the connecting rod can be driven by the hand-held hand wheel to rotate inside the second ejector rod through the bearing, meanwhile, the threaded rod is screwed and connected in a threaded groove, and the length between the first ejector rod and the second ejector rod is adjusted to the proper length through the depth of the threaded rod embedded in the threaded groove.
Description
technical field [0001] The invention belongs to the technical field of cylinder ejector devices, and in particular relates to a rock drilling jumbo propulsion cylinder ejector device. Background technique [0002] The existing oil cylinder ejector device is a part of the rock drilling rig and is the main body of the rock drilling rig. The oil cylinder ejector has sufficient strength and high stability during operation, which prolongs the service life of the oil cylinder ejector device and effectively improves the drilling efficiency. The operation efficiency of the rock trolley makes the operation better; the existing oil cylinder ejector device is not convenient to adjust the length of the ejector rod according to the use situation, which makes the operation inconvenient. When the frequent operation, the middle position of the ejector rod is suspended, The operation of the ejector rod is unstable, which affects the operation effect, and it is not convenient to protect the e...
