Abstract
A normal axis wrench suitable for a small operation space, comprises a wrench head and a wrench bar, wherein the outer end of the wrench head is provided with a general joint mated with a nut and the wrench head is connected with the wrench bar by the normal corner of a space gear mechanism and the space gear mechanism is formed by engaging a driving tapered gear with a driven tapered gear and covered by a corner shell and the driving tapered gear is fixed and connected with the wrench bar and the driven tapered gear is fixed and connected with the wrench head; a shell pressure cover is sleeved in the middle of the wrench head and the in screwed connection with the corner shell and a sleeve is sleeved on the wrench bar and in screwed connection with another part of the corner shell and a connection joint is arranged on the outer end of the wrench bar. The wrench has compact structure and relative long wrench bar and goes deep into very small space in the device; the required operation space of the wrench is very small and it is only necessary to make the wrench head extend into the device without swing space of the wrench bar. The wrench can cooperate with the manual wrench and dynamic wrench of all types and also cooperate with them by a lever.
Description
Technical field
The utility model relates to a kind of spanner.
Background technology
In coal mining equipment, because the restriction in space, the bolt of the fastening usefulness of many connections is all in a very little space, and some is far apart from operating personnel also at device interior, and dismounting is difficulty very.The present instruments such as spanner that use, though some can rely on the mode that increases extension bar deeply to device interior, but these spanners must have enough swing space ability complete operations, therefore its use is very restricted, when equipment keeps in repair with dismounting, run into above-mentioned problem and then all parts of influence operation can only be dismantled, increased work difficulty and working time greatly.
The utility model content
The purpose of this utility model provides a kind of vertical axis spanner that is applicable to little operating space, solve spanner in medium and small space or the restricted technical problem of the operation of plant equipment inside.
For achieving the above object, the utility model adopts following technical scheme:
A kind of vertical axis spanner that is applicable to little operating space, include spanner and tommy bar, wherein there is the universal joint that matches with nut the outer end of spanner, it is characterized in that: described spanner is connected by the vertical corner of space gear mechanism with tommy bar, described space gear mechanism is formed by drive bevel gear and driven wheel of differential engagement, its outside is covered with the corner housing, and drive bevel gear is fixedly connected on the tommy bar, and driven wheel of differential is fixedly connected on the spanner; Spanner middle part is with the housing gland, and the housing gland is threaded with the corner housing, is with sleeve on the tommy bar, and sleeve is threaded with another part of corner housing, and there is jointing the outer end of tommy bar.
Optimized technical scheme: the jointing of described tommy bar outer end can be circular hole that matches with lever and the universal joint that matches with the standard wrench socket.
Another technical scheme: the jointing of described tommy bar outer end also can be circular hole that matches with lever or the universal joint that matches with the standard wrench socket.
Compared with prior art the utlity model has following characteristics and beneficial effect:
The utility model is a kind of specific purpose tool that is used for the bolt and nut in the medium and small space of dismounting coal mine equipment, after bolt in spanner of the present utility model and the medium and small space or nut are locked, the rotation tommy bar can become flexible or screw bolt and nut, and do not need to swing tommy bar, so be applicable to medium and small operating space and plant equipment inside.
Advantage of the present utility model: 1. compact conformation, tommy bar is longer, can go deep into the very little space of device interior.2. the operation requisite space is minimum, as long as spanner can stretch into, tommy bar does not need to swing the space.3. can cooperate with all types of manual wrench and power operated wrench, can also use lever to cooperate with it.
Description of drawings
The utility model is described in more detail below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that schematic diagram is looked on the left side of Fig. 1.
Reference numeral: the universal joint that universal joint, 10-and the standard wrench socket that 1-spanner, 2-housing gland, 3-corner housing, 4-sleeve, 5-tommy bar, 6-drive bevel gear, 7-driven wheel of differential, 8-circular hole, 9-and nut match matches.
The specific embodiment
Embodiment is referring to Fig. 1, shown in Figure 2, this vertical axis spanner that is applicable to little operating space, include spanner 1 and tommy bar 5, wherein there is the universal joint 9 that matches with nut the outer end of spanner 1, spanner 1 is connected by the vertical corner of space gear mechanism with tommy bar 5, and described space gear mechanism is formed by drive bevel gear 6 and driven wheel of differential 7 engagements, and its outside is covered with corner housing 3, drive bevel gear 6 is fixedly connected on the tommy bar 5, and driven wheel of differential 7 is fixedly connected on the spanner 1; Spanner 1 middle part is with housing gland 2, and housing gland 2 is threaded with corner housing 3, be with sleeve 4 on the tommy bar 5, and sleeve 4 is threaded with another part of corner housing 3, and there is jointing the outer end of tommy bar 5, in the present embodiment, jointing is circular hole 8 that matches with lever and the universal joint 10 that matches with the standard wrench socket, certainly, in other embodiments, also can have only the circular hole 8 that matches with lever or have only the universal joint 10 that matches with the standard wrench socket.
Space gear mechanism in the present embodiment has adopted a cover bevel gear pair, and in addition according to actual needs, those skilled in the art also can adopt other space gear mechanism.Spanner and tommy bar axis are orthogonal, and bevel gear pair can be changed into vertical direction with the direction of rotation of tommy bar.One end of spanner and tommy bar is a bevel gear, and the length of tommy bar is bigger, can make series length as required, is convenient to stretch in the far little space operate, and a circular hole has also been designed in the outer end of tommy bar, can insert lever when needing.The bevel gear of spanner and tommy bar is installed in the corner housing, and the corner housing is provided with screw thread in the exit, and sleeve is connected with the corner housing by screw thread with the housing gland, compresses and support spanner and tommy bar.The housing gland can screw in the corner housing, works to compress and support spanner.Sleeve can screw in the corner housing, works to compress and support spanner.
Operation principle of the present utility model: the corner housing of earlier spanner and tommy bar being packed into, and bevel gear is coincide mutually.Housing gland and sleeve are screwed in the corner housing respectively, compress spanner and tommy bar, promptly finished the assembling of this new tool.
During use, the housing gland of standard is contained on the spanner, then spanner is stretched into device interior, coincide with the bolt and nut that will operate, with general utility wrench or lever turn tommy bar, bevel gear pair drives spanner in the direction rotation perpendicular to tommy bar, gets final product fastening and demounting bolt nut, and do not need to swing tommy bar, operation is very easy.
