Technical Field

The utility model relates to a CPIII point elevation measurement technical field especially relates to a chi of supplementary righting chi holds in palm.

Background

According to the perfection of the national high-speed rail network layout, the height measurement of the accurate measurement network adopts a matched measuring scale of a precise electronic level gauge. When other projects such as track projects and on-line projects are not carried out, the height measurement of the fine measuring net is started. At the moment, the sleeper and the ballast on the roadbed are not constructed, the CPIII column on the same foundation with the contact net is already constructed, the height of the CPIII point is determined according to the designed rail top, and the height of the CPIII point is higher than the chest of a person. Based on factors such as fall and wind, the staff holding the ruler can not ensure the verticality of the measuring ruler, thereby delaying the measuring progress and even leading to low accuracy of the measured data.

The utility model discloses the purpose is realized accomplishing by following technical scheme:

the utility model provides a chi of supplementary holding up ruler holds in palm for to the location of dipperstick, its characterized in that: the ruler support comprises a clamping piece, a connecting rod and a supporting piece, wherein the clamping piece is connected with the supporting piece through the connecting rod, the clamping piece is hinged with the connecting rod, and the connecting rod is hinged with the supporting piece; the clamping piece is provided with a clamping groove matched with the measuring scale in shape and size.

The joint spare with articulated between the connecting rod and articulated between connecting rod and the connecting rod are the ascending articulated of vertical side, make the joint spare with can produce the ascending relative displacement of direction of height between the connecting rod, make the connecting rod with can produce the ascending relative displacement of direction of height between the connecting rod.

And an anti-skid layer is arranged on the inner side surface of the clamping groove.

The utility model has the advantages that: the structure is simple, the measuring scale does not need to be improved, the cost is reduced, the later-stage disassembly is simple, and the scale support can be recycled; the ruler holding personnel are assisted to hold the ruler, so that the operation difficulty of the ruler holding personnel is reduced; the measuring scale is in verticality, so that the reading precision is improved; the support member has a high degree of conformity with the CPIII post.

fig. 2 is a sectional view taken along line a-a of fig. 1.

Detailed Description

The features of the present invention and other related features are described in further detail below by way of example in conjunction with the accompanying drawings to facilitate understanding by those skilled in the art:

as shown in fig. 1-2, the symbols 1-7 in the figures are respectively represented as: joint spare 1, connecting rod 2, support piece 3, pivot 4, pivot 5, draw-in groove 6, dipperstick 7.

Example (b): the embodiment is a ruler support for assisting a ruler to be supported, and is particularly suitable for CPIII point elevation measurement.

Referring to fig. 1 and 2, the ruler support includes a clip member 1 and a connecting rod 2.

Wherein, the left side of joint spare 1 is equipped with draw-in groove 6, and the identical adaptation of the outline of the shape size of draw-in groove 6 and dipperstick 7 can realize the joint operation in the later stage imbeds draw-in groove 6, need not to improve dipperstick 7, and reduce cost and later stage are dismantled simply, and joint spare 1 can cyclic utilization.

Combine figure 1, 2 to show, the right-hand member of joint spare 1 is connected with connecting rod 2, and when the later stage was surveyed net height and is measured accurately, the holding up the chi personnel only need arrange the bottom surface of dipperstick 7 in CPIII point on the spheroid to swing dipperstick 7 make the right-hand member of connecting rod 2 support on CPIII post can, can assist the holding up the chi personnel to hold up the chi, reduce the operation degree of difficulty of holding up the chi personnel. The connecting rod 2 is specifically connected to the right side of the clamping piece 1 through the rotating shaft 5 and the nut, the connecting rod 2 can rotate around the rotating shaft 5, so that the included angle between the connecting rod 2 and the clamping piece 1 is changed, the distance from a measuring scale 7 at the clamping position to the CPIII column can be equal to the distance from the bottom surface of the measuring scale 7 to the CPIII column, the verticality of the measuring scale 7 is ensured, and the reading precision is improved; the ruler support can be recycled and is convenient to store.

Along with the rotation of connecting rod 2, its binding face with the CPIII post diminishes, and the laminating effect is poor. As shown in fig. 1 and 2, support piece 3 is connected at the right-hand member of connecting rod 2 through pivot 4 and nut, and support piece 3 can be rotatory round pivot 4 to change support piece 3 and connecting rod 2's contained angle, only need during the use adjust support piece 3 make support piece 3's the right flank parallel with the left surface of CPIII post can, improve both laminating degrees, thereby improve the support effect to dipperstick 7 that the chi held in the palm.

The operation steps of this embodiment are as follows:

1) the side wall of the measuring scale 7 is embedded into the clamping groove 6;

2) adjusting the support 3 so that the right side of the support 3 is parallel to the left side of the CPIII column;

3) adjusting the connecting rod 2, and changing an included angle between the connecting rod 2 and the clamping piece 1; so that the distance from the right side surface of the measuring scale 7 at the clamping position to the right side surface of the support piece 3 is equal to the distance from the right side surface of the bottom surface of the measuring scale 7 to the left side surface of the CPIII column;

4) the steps 2) and 3) are carried out simultaneously;

5) after the measurement is finished, the measuring scale 7 is taken out of the clamping groove 6, the connecting rod 2 is adjusted to accommodate the scale support, and the space occupancy rate is saved;

6) and (5) circulating the steps 1) to 5) to realize the recycling of the ruler support.

In the embodiment, in specific implementation:

as shown in fig. 1, the rotation shafts 4, 5 are arranged along the width direction of the connecting rod 2, and rotating the connecting rod 2 causes the connecting rod 2 to displace in the height direction. The axis direction of pivot 4, 5 can be adjusted by oneself according to the in service behavior, only need guarantee through adjusting connecting rod 2 can make the distance between joint spare 1 and the support piece 3 change can.

The inner side surface of the clamping groove 6 is provided with an anti-skid layer (not shown in the figure), so that the friction on the outer wall of the measuring scale 7 is reduced, and the metal on the scale surface of the measuring scale 7 is protected from being abraded.

The ruler support is made of light aluminum alloy and the like.

Although the conception and the embodiments of the present invention have been described in detail with reference to the drawings, those skilled in the art will recognize that various changes and modifications can be made therein without departing from the scope of the appended claims.
