Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1-5, the portable support for a bridge and tunnel measuring instrument provided by the present invention comprises a storage cylinder 1, a supporting foot seat 2, a supporting foot 3, a height-adjusting slide bar 4 and a measuring instrument support 5; the storage barrel 1 is of a hollow structure, the lower end of the storage barrel is provided with an opening with a flange 101 at the edge, and the upper end of the storage barrel is protruded to form a guide ring 102; the supporting foot seat 2 is arranged in the containing cylinder 1 in a manner of sliding up and down, can be fixed in position, and is limited by the flanging 101 so as to prevent the supporting foot seat 2 from sliding out of the containing cylinder 1; the upper ends of the three support legs 3 are uniformly hinged on the bottom surface of the support leg seat 2; the height-adjusting slide bar 4 is inserted into the housing 1 from the guide ring 102 at its lower end and fixed in position, and has its upper end connected to the gauge stand 5.

Two second elastic clamping blocks 21 are symmetrically arranged on the side wall of the supporting foot seat 2.

A jackscrew 103 is arranged on the side wall of a guide ring 102 on the storage barrel 1, the jack screw 103 is screwed down to push the height-adjusting slide bar 4 tightly, so that the position between the height-adjusting slide bar 4 and the storage barrel 1 is fixed, and the extension length of the height-adjusting slide bar 4 can be adjusted by loosening the jack screw 103; two through holes for clamping the second elastic clamping block 21 are symmetrically formed in the side wall of the lower part of the containing barrel 1; when the second elastic fixture block 21 is clamped into the through hole, the position between the storage barrel 1 and the support foot seat 2 can be locked; after the second elastic latch 21 is pressed inward with a force, the locking state between the storage tube 1 and the stand 2 can be released, thereby realizing the free sliding of the stand 2.

The upper end of the supporting leg 3 is hinged with the supporting leg base 2 through a bolt and a nut, and the rotating flexibility of the supporting leg 3 can be adjusted to the most suitable state through adjusting the screwing degree of the nut.

Sometimes the measured position may be uneven, and at this time the portable stand needs to be leveled, therefore, the support legs 3 are telescopic support legs, including a support leg tube 6 and a support leg rod 7; the upper end of the supporting leg tube 6 is hinged on the supporting leg seat 2, and a plurality of through holes are uniformly arranged on the side wall along the axis direction; the upper part of the supporting leg rod 7 is inserted into the supporting leg pipe 6 from the lower part, and the side wall of the upper part is provided with a first elastic clamping block 61 which can be clamped in any through hole on the supporting leg pipe 6; when the first elastic clamping block 61 is clamped into the through hole, the position between the support leg tube 6 and the support leg rod 7 can be locked; when the first elastic latch 61 is pressed inward with a force, the locked state between the leg tube 6 and the leg bar 7 can be released, thereby achieving the free sliding of the leg bar 7.

The stretching of the three support legs 3 can only realize rough adjustment for leveling, so that the portable support can be placed stably as a whole, but the fine adjustment is carried out by using the support 5 of the measuring instrument when the measuring instrument placed on the portable support reaches the leveling standard, therefore, the support 5 of the measuring instrument comprises a first support disc 8, a second support disc 9 and a plurality of bidirectional screws 10; the middle part of the bottom surface of the first supporting disk 8 is fixed at the upper end of the height-adjusting slide rod 4, the second supporting disk 9 is arranged above the first supporting disk 8, and a plurality of screw holes which are symmetrically distributed and correspond up and down are formed on the outer circumferences of the first supporting disk 8 and the second supporting disk 9; each two-way screw 10 is simultaneously in threaded connection with one corresponding screw hole of the first supporting disk 8 and the second supporting disk 9, and a screwing handle for micro leveling is arranged on the two-way screw 10 between the first supporting disk 8 and the second supporting disk 9; due to the fact that the thread directions of the upper portion and the lower portion of the bidirectional screw 10 are opposite, the distance between the first supporting plate 8 and the second supporting plate 9 can be adjusted by rotating the screwing handle, and therefore micro-leveling is achieved.

In order to prevent the interference between the lower part of the height-adjusting slide bar 4 and the support base 2 in the receiving tube 1, a through hole is arranged at the center of the support base 2, and the diameter of the through hole is larger than that of the height-adjusting slide bar 4, so that the height-adjusting slide bar 4 can pass through the through hole.

In order to further improve the convenience of carrying, a handle 11 and a strap ring 12 are further provided on the side wall of the storage tube 1, and a strap can be attached to the strap ring 12, so that the storage tube can be carried on the shoulder.

The portable support for the bridge and tunnel measuring instrument further comprises a barrel cover 13 sleeved on the outer side of the lower portion of the containing barrel 1.

As shown in fig. 6, the structures of the first elastic latch 61 and the second elastic latch 21 are the prior art, and are commonly used in various mechanical structures or daily products, and detailed description thereof is omitted.

Will now the utility model provides a portable support for bridge tunnel measuring apparatu's use method explains as follows:

when the position reaches the measuring position, firstly, a measurer opens the barrel cover 13 and pulls out the support leg 3 until the second elastic fixture block 21 is clamped into the through hole on the side wall of the lower part of the containing barrel 1, so that the position between the support leg seat 2 and the containing barrel 1 is fixed; then, the opening angles of the three support legs 3 are adjusted, and then the support leg rod 7 is pulled out until the first elastic fixture block 61 is clamped into a proper through hole on the support leg pipe 6, so that the whole portable support is adjusted to be in a roughly balanced and stable state; a measuring instrument is fixed on the second supporting plate 9, and then the extending length of the height-adjusting slide rod 4 is adjusted and is tightly pressed by a jackscrew 103; then the screwing handle on the bidirectional screw 10 is turned to adjust the distance between the first support disc 8 and the second support disc 9, thereby achieving micro-leveling. At this time, the measuring instrument can be used for measuring, and when the positions with different heights are measured, only the height-adjusting sliding rod 4 needs to be adjusted.

When the measurement is completed, the supporting feet 3 and the height-adjusting sliding rods 4 are all collected into the containing cylinder 1, and the cylinder cover 13 is covered, so that the next surveying point can be carried.
