The tripod device for reducing friction force consists of a rack, the tripod and a bearing; the rack is mounted at the top end of the tripod; and the bearing is mounted at the middle part of the rack. The tripod device for reducing friction force has the beneficial effect of capability of flexibly rotating the measuring instrument on the tripod.
Description
Technical field
The present invention is to reduce A-frame device and the way of frictional force, is for making measuring instrument turn flexibly on spider
Move and design, belong to construction account field.
Background technology
Measuring spider is used to set up the precision instrument and equipments such as theodolite, level gauge or total powerstation；Existing
The stand end face of measuring spider smooth, contact with the end face of measuring instrument, owing to contact surface is big, frictional force
Greatly, rotating frequently, make instrument rotate less flexible, friction will also result in the damage of equipment, and for precision instrument, these are all
Existing problems；The A-frame device of the minimizing frictional force that the present invention provides and way, can solve these problems.
Summary of the invention
The specific practice of this programme is:
The A-frame device and the way that reduce frictional force are to increase axle in the end face middle part of the stand 1 of existing spider
Hold, so that it may so that the equipment being arranged on stand 1 rotates flexibly；Reduce the A-frame device of frictional force and way by stand 1,
Spider 2 and bearing 3 composition；Stand 1 is arranged on the top of spider 2；Bearing 3 is arranged on the middle part of stand 1.
Stand 1 is the pedestal setting up the equipment such as theodolite, level gauge of triangular prism shape, and middle porose, bearing 3 is arranged on hole
In；The axle of measuring instrument is connected with spider by the hole in the middle of bearing 3；The bottom triangle portion of stand 1 is with spider 2 even
Connect.
Spider 2 is made up of lower limb under lower limb, support on support and tough foot；On support, lower limb is middle slotted rod-like members,
On support, the length of the groove of lower limb is equal to the length of lower limb under support, and on support, the width of the groove of lower limb is equal to the thickness of lower limb under support；?
Under frame, lower limb is rod-like members, under support in the groove of the rack-mount lower limb of lower limb；On support, the top of lower limb is connected with stand 1.
Bearing 3 is the critical component making measuring instrument flexible rotating, the hole employing interference fits that bearing 3 is middle with stand 1；
The aspect ratio stand 1 high 0.1-0.2 millimeter of the upper surface of bearing 3.
The way of A-frame device reducing frictional force with way is, at the position of interstitial hole of stand 1 by existing sky
Hole expands, and the new hole expanded is the most concentric with foramen primum, and the diameter in hole is identical, partially with the external diameter basic size of selected bearing 3
Difference is at 0 ,-0.02 millimeter；The working depth in hole is identical with bearing thickness, and deviation is-0.1 ,-0.2 millimeter；Hole processing progress is full
After foot requires, bearing 3 is pressed into the position of the interstitial hole of stand 1.
The invention has the beneficial effects as follows and can make measuring instrument flexible rotating on spider.
Accompanying drawing explanation
Fig. 1 reduces A-frame device and the way schematic diagram of frictional force；
In figure: 1-stand；2-spider；3-bearing.
Detailed description of the invention
Embodiment
Certain engineering uses A-frame device and the way of minimizing frictional force as shown in Figure 1, reduces the triangle of frictional force
Holder device and way are to increase bearing in the end face middle part of the stand 1 of existing spider, so that it may so that being arranged on stand 1
On equipment rotate flexibly；The A-frame device and the way that reduce frictional force are made up of with bearing 3 stand 1, spider 2；
Stand 1 is arranged on the top of spider 2；Bearing 3 is arranged on the middle part of stand 1.
Stand 1 is the pedestal setting up the equipment such as theodolite, level gauge of triangular prism shape, and middle porose, bearing 3 is arranged on hole
In；The axle of measuring instrument is connected with spider by the hole in the middle of bearing 3；The bottom triangle portion of stand 1 is with spider 2 even
Connect.
Spider 2 is made up of lower limb under lower limb, support on support and tough foot；On support, lower limb is middle slotted rod-like members,
On support, the length of the groove of lower limb is equal to the length of lower limb under support, and on support, the width of the groove of lower limb is equal to the thickness of lower limb under support；?
Under frame, lower limb is rod-like members, under support in the groove of the rack-mount lower limb of lower limb；On support, the top of lower limb is connected with stand 1.
Bearing 3 is the critical component making measuring instrument flexible rotating, the hole employing interference fits that bearing 3 is middle with stand 1；
The aspect ratio stand 1 high 0.1-0.2 millimeter of the upper surface of bearing 3.
The way of A-frame device reducing frictional force with way is, at the position of interstitial hole of stand 1 by existing sky
Hole expands, and the new hole expanded is the most concentric with foramen primum, and the diameter in hole is identical, partially with the external diameter basic size of selected bearing 3
Difference is at 0 ,-0.02 millimeter；The working depth in hole is identical with bearing thickness, and deviation is-0.1 ,-0.2 millimeter；Hole processing progress is full
After foot requires, bearing 3 is pressed into the position of the interstitial hole of stand 1.
