Abstract
The utility model discloses a tower upper-platform head sheave moving device which is composed of the following components: a head sheave, a head sheave shaft, a left half part of a split type bearing seat, a right half part of a split type bearing seat, a support, an upper platform, a sleeve and a moving platform. The head sheave rotates relative to the head sheave shaft. The split type bearing seat is closely combined with two ends of the head sheave shaft for closely fixing the head sheave shaft. The split type bearing seat is fixed at the front end of the upper surface of the moving platform of the tower. The sleeve is welded on the top end of the head sheave shaft. The upper platform is connected with the moving platform through the support. The split type bearing seat is divided into two half parts, namely the right half part and the right half part. In normal operation, the split type bearing seat is fixed at the front end of the upper platform of the tower for fastening the head sheave shaft; and in maintenance, the right half part of the split type bearing seat is detached and is afterwards fixed at the back end of the moving platform, thereby preventing rolling of the head sheave and the head sheave shaft from the moving platform. The tower upper-platform head sheave moving device has the advantages of simple structure, convenient manufacture and safe operation. Problems of time/labor wasting and low safety in maintenance of the tower type pumping unit are settled.
Description
Technical field
The utility model relates to petroleum machinery pumping unit field, specifically relates to a kind of pylon upper mounting plate head sheave mobile device of tower shelf type oil pumping machine.
Background technology
Tower shelf type oil pumping machine is in operation, occur that sometimes Ka Jing or well head drive the phenomenon of rope job-hopping, now need staff upper to tower top platform outside repair, because pylon is higher, head sheave must be removed to pithead position, will head sheave be unloaded with large-scale crane, after to be trimmed getting well, again head sheave is fixed, waste time and energy, and staff is also dangerous.
Summary of the invention
The problems referred to above that exist in order to solve existing tower shelf type oil pumping machine, the utility model provides a kind of can unload head sheave without crane, but head sheave is moved to the pylon upper mounting plate head sheave mobile device that gets out of the way pithead position to platform rear end.
Technical scheme: pylon upper mounting plate head sheave mobile device is comprised of head sheave, day wheel shaft, split type bearing support left side, split type bearing support right-hand part, support, upper mounting plate, sleeve pipe, mobile platform, head sheave is rotated with respect to sky wheel shaft, split type bearing support is combined closely with day wheel shaft two ends, sky wheel shaft is tightly fixing, split type bearing support is fixed on the front end above pylon mobile platform, the top of it wheel shaft is welded with sleeve pipe, between upper mounting plate and mobile platform, be by support and connection, described split type bearing support is left, right two halves, during normal operation, be fixed on the front end of pylon upper mounting plate, for fastening day wheel shaft, during maintenance, the right half part of split type bearing support is pulled down, be fixed on subsequently the rear end of mobile platform, prevent that head sheave and day wheel shaft from tumbling from mobile platform.
The beneficial effects of the utility model are: simple in structure, easy to make, handling safety, has reached wasting time and energy and unsafe problem of existing while solving tower shelf type oil pumping machine maintenance.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In Fig. 1,1. head sheave, 2. split type bearing support left side, 3. split type bearing support right-hand part, 4. supports, 5. upper mounting plate, 6. sleeve pipe, 7. day wheel shaft, 8. mobile platform.
The specific embodiment
Under normal circumstances, the split type bearing support left side (2) of tower shelf type oil pumping machine and split hand bearing support right-hand part (3) are fixed on the front end of mobile platform (8), and tightly fix a day wheel shaft (7), so that head sheave (1) is rotated, when occurring that Ka Jing or well head drive rope job-hopping, pull down split type bearing support right-hand part (3), then split type bearing support right-hand part (3) is fixed on to the rear end of mobile platform (8), with crowbar, be through in the sleeve pipe (6) on a day wheel shaft (7) top, rotate a day wheel shaft (7), the rear end that sky wheel shaft (7) drive head sheave (1) is moved to mobile platform (8) is near split type bearing support right-hand part (3), now, head sheave (1) is got out of the way pithead position, staff may stand in safety on upper mounting plate and carries out maintenance work.
Claims (1)
1. pylon upper mounting plate head sheave mobile device is comprised of head sheave, day wheel shaft, split type bearing support left side, split type bearing support right-hand part, support, upper mounting plate, sleeve pipe, mobile platform; It is characterized in that: the head sheave of described pylon upper mounting plate head sheave mobile device is rotated with respect to sky wheel shaft, split type bearing support is combined closely with day wheel shaft two ends, sky wheel shaft is tightly fixing, split type bearing support is fixed on the front end above pylon mobile platform, the top of it wheel shaft is welded with sleeve pipe, between upper mounting plate and mobile platform, is by support and connection; Described split type bearing support is left and right two halves, while normally moving, is fixed on the front end of pylon upper mounting plate, for fastening day wheel shaft, during maintenance, the right half part of split type bearing support is pulled down, be fixed on subsequently the rear end of mobile platform, prevent that head sheave and day wheel shaft from tumbling from mobile platform.
