Description

Technical Field

[0001] This invention belongs to the field of optical surveying technology, specifically relating to a sliding rail theodolite maintenance support device and its usage method. Background Technology

[0002] Theodolites, as important precision optical surveying instruments, are widely used in military and civilian fields such as bridge construction, tunneling, and equipment aiming. They typically consist of a base, a leveling system, an optical alignment system, and a reading system. When the leveling feet on the theodolite malfunction, the theodolite needs to be placed on its side to allow the set nuts on the theodolite base to be removed for troubleshooting and repair.

[0003] Currently, theodolites are usually placed on their side on a flat table for disassembly and maintenance of the base. This lateral support method is simple and convenient for medium and low precision small theodolites, but it is not suitable for high precision medium and large theodolites. The main reasons are as follows:

[0004] First, the external structure of the theodolite is irregular in shape, making it difficult to find suitable and stable support points;

[0005] Secondly, the theodolites are relatively heavy, and the lateral support method can easily damage the micrometer components, horizontal locking components, and other parts of the theodolites, causing irreversible physical damage.

[0006] For the maintenance of high-precision medium and large theodolites, the pad support method is generally used. This means that a wooden or iron block is placed at a suitable position on the side of the theodolite for support. This pad support method effectively protects the precision mechanical parts of the theodolite, such as the micrometer and locking device. However, at the same time, the risk of the theodolite slipping or rolling and being damaged is also relatively high.

[0007] Therefore, this invention believes it is necessary to design a base maintenance support device for medium and large theodolites. Summary of the Invention

[0008] The purpose of this invention is to solve the technical problem that existing side-mounted supports or pad supports pose a risk of damage or slippage when repairing medium and large theodolites. The invention provides a sliding rail type theodolite repair support device and its usage method, which aims to improve the stability of the support during theodolite repair process and reduce the risk of theodolite damage.

[0009] To achieve the above objectives, the technical solution provided by this invention is as follows:

[0010] A sliding rail type theodolite maintenance support device is characterized by including a base plate and an inclined clamping mechanism.

[0011] The bottom plate is rectangular, and a guide rail groove is provided in the middle along the length direction (that is, the guide rail groove is located on the center line of the bottom plate); a groove with both ends open is provided in the middle of the bottom surface of the bottom plate along the length direction (similarly, the groove is also located on the center line of the bottom plate, and obviously, the width of the groove is greater than the width of the guide rail groove); a limit block is provided at one end of the upper surface of the bottom plate opposite to the guide rail groove. The limit block is rectangular parallelepiped and is installed on the surface of the bottom plate by means of a set screw and a threaded hole.

[0012] The tilt clamping mechanism is used to adjust the tilt angle of the theodolite to be repaired and stably clamp the theodolite to be repaired, and includes a sliding support assembly and two sets of width-adjustable clamping assemblies.

[0013] The sliding support assembly includes a support plate, a sliding locking member, two ball rail guides and two auxiliary rail guides.

[0014] The two ball rail guides are installed on the upper surface of the bottom plate and are symmetrically arranged relative to the guide rail groove; the two auxiliary rail guides are installed in the groove on the bottom surface of the bottom plate and are symmetrically arranged relative to the guide rail groove; the two auxiliary rail guides cooperate with the guide rail groove to form a limit chute for guiding the support plate and the sliding locking member; the above-mentioned groove can not only provide an installation space for installing the two auxiliary rail guides, but also reduce the weight of the bottom plate to a certain extent; the height of the auxiliary rail guide is not greater than the depth of the groove, and its installation will not affect the stable placement of the bottom plate.

[0015] The support plate is in a "C" shape and includes a cross beam and two wing plates respectively vertically arranged at both ends of the cross beam; sliding chutes adapted to the two ball rail guides are provided on the bottom surfaces of the two wing plates, and a through hole is provided in the middle of the cross beam; the whole support plate is installed on the bottom plate by a sliding locking member and can slide and lock on the bottom plate along the limit chute and the ball rail guides.

[0016] The two sets of clamping assemblies are symmetrically installed on the two wing plates of the support plate.

[0017] Each set of clamping assemblies includes a rib plate, a clamping plate, a connecting adjustment member and a supporting adjustment member; the rib plate is installed on the wing plate and is perpendicular to the bottom plate, and the two rib plates face each other; the clamping plate is installed on the inner panel of the rib plate by the connecting adjustment member; with the assistance of the connecting adjustment member, the distance between the clamping plate and the rib plate is adjustable; the supporting adjustment member is installed on the clamping plate, and its height on the clamping plate is adjustable; when clamping the theodolite to be repaired, the supporting surface of the supporting adjustment member is in surface contact with the theodolite to be repaired. It is defined that the side close to the center line of the bottom plate is the inner side, and the side far from the center line of the bottom plate is the outer side.

[0018] One end of the theodolite to be repaired is placed on the bottom plate and is limited by the limit block, and the other end is stably clamped by the two sets of clamping assemblies after the tilt angle is adjusted by the sliding support assembly according to the repair requirements.

[0019] Furthermore, the ball bearing slide rail is elongated and narrower at the top than at the bottom, providing excellent load-bearing capacity. A circular groove is formed along its length at the top, and balls are placed sequentially in the groove to allow the wing plate to slide smoothly. The bottom is fixed to the base plate by a combination of set screws and threads.

[0020] The bottom of the wing plate has a hemispherical groove adapted to the ball bearing, and the entire support plate can slide freely on the slide rail with the assistance of the wing plate.

[0021] Furthermore, the auxiliary slide rail, viewed from the shaft end, is... The type includes a vertical plate and an upper and lower horizontal plate that are vertically installed on both sides of the vertical plate; wherein, the auxiliary slide rail is connected to the base plate through the upper horizontal plate (connected by a set screw and a threaded hole).

[0022] The two auxiliary slide rails are symmetrically arranged, and the overall shape is as shown when viewed from the shaft end. The shape has a gap between the two lower horizontal plates;

[0023] The two lower horizontal plates, the two vertical plates, the bottom of the base plate groove, and the guide rail groove work together to form the limiting slide.

[0024] Furthermore, the sliding locking component includes a base plate slider, a locking bolt, and a locking nut;

[0025] The base plate slider is located in the limiting groove and includes a main body and two side plates; the main body is a hollow cylinder with internal threads, and the two side plates are symmetrically arranged on both sides of the main body; the side plates are "T" shaped, and the main body is convex relative to the side plates;

[0026] The locking bolt is located at the through hole of the crossbeam, and its upper and lower ends are provided with reverse threads; the upper end is threadedly connected to the locking nut, and the lower end is threadedly connected to the main body of the base plate slider; the locking bolt is equivalent to the core of the entire sliding locking component; when the locking nut is loosened, the support plate can move along the limiting groove, and when the locking nut is tightened, the support plate is limited on the base plate.

[0027] Furthermore, the vertical cross-section of the rib plate is inverted "T" shape, and its bottom is connected to the wing plate by a combination of a set screw and a threaded hole. An installation through hole is provided on the plate surface near the top along the center line. In order to make the load-bearing capacity of the entire rib plate more reliable, a reinforcing plate is provided at both ends of the rib plate, and the reinforcing plate is in the shape of an isosceles trapezoid.

[0028] The connecting adjustment component includes a thin-walled internally threaded cylinder, a thin-walled through-hole cylinder, a width adjustment bolt, and four guide rail cylinders.

[0029] The thin-walled internally threaded cylinder and the thin-walled through-hole cylinder are respectively set (which can be set by welding) at both ends of the through hole on the rib plate, and the inner diameter of the thin-walled internally threaded cylinder and the thin-walled through-hole cylinder are the same as the diameter of the through hole; the thin-walled through-hole cylinder is located on the inner side of the rib plate.

[0030] The width adjusting bolt passes through the thin-walled internally threaded cylinder and the mounting through hole from the outside to the inside, and extends into the thin-walled through hole cylinder. The width adjusting bolt is threadedly engaged with the thin-walled internally threaded cylinder.

[0031] The four guide rail cylinders are vertically arranged (which can be set by welding) on ​​the inner side of the rib plate, serving as the four ends of the same rectangle, and the thin-walled through-hole cylinder is located at the center point of the rectangle. That is, the four guide rail cylinders are arranged in pairs, symmetrically with respect to the thin-walled through-hole cylinder; each guide rail cylinder has a limit screw hole for installing limit screws on the cylindrical surface near the end face.

[0032] The support adjustment component includes a thin-walled sleeve, four width limiting slide rails, two support rods, two support rod bolts, and four guide rail sleeves.

[0033] The thin-walled sleeve and four guide rail sleeves are mounted on the clamping plate (which can be installed by welding). The installation position is determined according to the position of the thin-walled through-hole cylinder and the four guide rail cylinders. After the guide rail sleeve and the thin-walled sleeve are installed, the guide rail cylinder and the thin-walled through-hole cylinder can move back and forth within the guide rail sleeve and the thin-walled sleeve. That is, the thin-walled sleeve and the four guide rail sleeves are clearance-fitted with the thin-walled through-hole cylinder and the four guide rail cylinders on the inner side of the rib plate. Each guide rail sleeve is provided with a through guide groove. The limiting screw installed on the guide rail cylinder can move axially within the through guide groove to prevent the guide rail sleeve from detaching from the guide rail cylinder.

[0034] The bolt length of the width adjusting bolt is approximately equal to the sum of the length of the thin-walled internally threaded cylinder, the length of the thin-walled through-hole cylinder, the length of the thin-walled sleeve, and the thickness of the rib plate at the mounting through-hole.

[0035] The clamping plate is a rectangular plate with two elongated guide grooves on its center line, i.e., the elongated guide grooves are vertical grooves, located above and below the thin-walled sleeve respectively; two width limiting slide rails (which can be installed by welding) are symmetrically arranged on both sides of each elongated guide groove; the width limiting slide rails are L-shaped when viewed from the shaft end, and the two width limiting slide rails, together with the clamping plate and the elongated guide grooves, form a slide groove structure to limit the movement of the support rod bolts;

[0037] Furthermore, the support rod adopts a multi-faceted cylindrical structure, and its end face contacts the surface of the theodolite during maintenance; the other end of the support rod has an axially threaded hole for threaded connection with the support rod bolt.

[0038] Furthermore, the upper end of the locking bolt is engraved with a clockwise thread, and the lower end is engraved with a counterclockwise thread;

[0039] The locking nut has a clockwise thread engraved inside;

[0040] The body of the base plate slider is engraved with counterclockwise threads.

[0041] Meanwhile, the present invention also provides an installation method for a sliding rail type theodolite maintenance support device, which is characterized by including the following steps:

[0042] 1) Assemble the sliding support assembly:

[0043] Fix the limiting block to the upper surface of the base plate;

[0044] Two ball bearing slide rails are symmetrically installed on the upper surface of the base plate relative to the guide rail groove of the base plate;

[0045] Two auxiliary slide rails are symmetrically installed at the bottom of the groove on the bottom surface of the base plate relative to the guide rail groove of the base plate to form a limiting slide groove;

[0046] Insert the two wing plates of the support plate into the two ball bearing slide rails respectively, and use the sliding locking device to connect the crossbeam of the support plate into the limiting slide groove to complete the assembly of the sliding support assembly;

[0047] 2) Assemble two sets of adjustable-width clamping components.

[0048] The clamp plate with the support adjustment component is installed on the rib plate with the connecting adjustment component to complete the assembly of two sets of width-adjustable clamping components.

[0049] 3) Complete the installation of the sliding rail type theodolite maintenance support device.

[0050] Two sets of adjustable-width clamping components are vertically installed on the two wing plates of the support plate through their respective ribs, thus completing the installation of the sliding rail theodolite maintenance support device.

[0051] Furthermore, the method of using the aforementioned sliding rail type theodolite maintenance support device is unique in that it includes two steps in sequence: support position adjustment and tilt angle adjustment.

[0052] The specific adjustment of the support position is as follows:

[0053] Step 1: Place the assembled sliding rail theodolite maintenance support device on a flat surface;

[0054] Step 2: Secure the support plate to the base plate using the sliding locking mechanism;

[0055] Step 3: Adjust the distance between the clamping plates of the two sets of clamping components by adjusting the connecting adjustment parts according to the width of the theodolite to be repaired, so as to ensure that the theodolite to be repaired is centered;

[0056] Step 4: Based on the position of the adjustment knob and operation panel on the theodolite to be repaired, adjust the height of the two support adjustment components on their respective clamps so that the support surfaces of the two support adjustment components avoid the adjustment knob and operation panel on the theodolite to be repaired.

[0057] Step 5: Place the theodolite to be repaired at an angle on the sliding rail theodolite repair support device, with one end placed on the base plate and limited by the limiting block, and the other end placed between the two sets of clamping components;

[0058] Step 6: Fine-tune the connecting adjustment components to ensure that the theodolite to be repaired is securely supported between the two sets of clamping components;

[0059] The tilt angle adjustment is as follows:

[0060] Loosen the sliding locking element, push the support plate along the limiting groove and ball bearing slide rail on the base plate, thereby causing the two sets of clamping components to slide accordingly. Adjust the tilt angle of the theodolite to be repaired until the required angle is met, then tighten the support plate again using the sliding locking element. After that, normal maintenance can be performed.

[0061] The advantages of this invention are:

[0062] 1. This invention designs a theodolite maintenance support device, filling the gap in standard support devices for the bottom maintenance of theodolites. It is highly versatile and applicable not only to medium and large theodolites but also to small theodolites. Through the cooperation of the base plate and the tilting clamping mechanism, it can achieve reliable and firm support for the theodolite to be maintained, effectively reducing the risk of slippage or rolling damage during maintenance. The adjustable width design can adapt to the support needs of different models of theodolites to be maintained, and the adjustable tilt angle can meet the maintenance needs of different parts.

[0063] 2. The overall structure of this invention is ingeniously designed, and it is very convenient to install and use. By changing the contact method of the support position from line support to surface support, the stability of the support is greatly improved.

[0064] 3. The device of the present invention has strong functional expandability. In addition to meeting the needs of theodolite maintenance, it can also be used to support other equipment to be maintained. Attached Figure Description

Detailed Implementation

[0078] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0079] This invention discloses a sliding rail type theodolite maintenance support device, comprising a base plate and an inclined clamping mechanism. The base plate provides support and a mounting foundation. The inclined clamping mechanism adjusts the tilt angle of the theodolite to be repaired and stably clamps it. It includes a sliding support assembly 1 and two sets of adjustable-width clamping assemblies 2, which are fixedly connected by screws. Figure 1 The two dashed boxes in the middle respectively circle the main components of the sliding support assembly 1 and the two sets of adjustable width clamping assemblies 2.

[0080] like Figure 2 As shown, the base plate 1-1 is rectangular, and a groove with open ends is formed on the center line of its bottom surface along the length direction; a guide rail groove 1-1-2 is formed on the center line of the bottom of the groove, and a row of third threaded holes 1-1-4 are respectively provided on both sides of the guide rail groove 1-1-2; two rows of first threaded holes 1-1-1 are respectively provided on the two sides of the surface of the base plate 1-1 symmetrical about the guide rail groove 1-1-2, and three second threaded holes 1-1-3 are provided at one end of the surface of the base plate 1-1.

[0081] The limit block 1-4 is in the shape of a cuboid, with three threaded through-holes 1-3-1 in the middle, which cooperate with the second threaded holes 1-1-3 on the surface of the bottom plate 1-1, and are fixed to one end of the surface of the bottom plate 1-1 facing the guide rail groove by set screws.

[0082] The sliding support assembly includes a support plate 1-3, a sliding locking member, two ball rails 1-2 and two auxiliary rails 1-8.

[0083] As Figure 3 shown, the ball rail 1-2 is strip-shaped, wider at the bottom and narrower at the top, with good bearing capacity. A row of first threaded through-holes 1-2-2 are respectively opened on both sides of its bottom, which cooperate with the first threaded holes 1-1-1 on the surface of the bottom plate 1-1. A circular groove is opened along the length direction at the top, and balls 1-2-2 are sequentially placed in the groove; the two ball rails 1-2 are installed on the surface of the bottom plate 1-1 by set screws and are symmetrically arranged relative to the guide rail groove 1-1-2.

[0084] As Figure 5 shown, the auxiliary rail 1-8 is in an L shape when viewed from the shaft end, including a vertical plate and upper and lower cross plates vertically arranged on both sides of the vertical plate, and is an integral part; among them, a row of second threaded through-holes 1-8-1 are arranged along the length direction on the upper cross plate, which cooperate with the third threaded holes 1-1-4 at the bottom of the groove of the bottom plate 1-1. The auxiliary rail 1-8 is connected to the bottom plate 1-1 by set screws; the two auxiliary rails 1-8 are symmetrically installed in the groove on the bottom surface of the bottom plate 1-1 relative to the guide rail groove 1-1-2, and as a whole, it is in an L shape when viewed from the shaft end, and there is a gap between the two lower cross plates; the two lower cross plates, together with the two vertical plates, the bottom of the groove of the bottom plate 1-1 and the guide rail groove 1-1-2, jointly form a limiting chute for guiding the support plate and the sliding locking member. The groove on the bottom surface of the bottom plate 1-1 can not only provide an installation space for installing the two auxiliary rails 1-8, but also reduce the weight of the bottom plate 1-1 to a certain extent, and the installation of the auxiliary rails 1-8 will not affect the stable placement of the bottom plate 1-1.

[0085] As Figure 4 shown, the support plate 1-3 is in a "C" shape, including a cross beam and two wing plates respectively vertically arranged at both ends of the cross beam, and is an integral part; hemispherical grooves adapted to the balls 1-2-2 are arranged at the bottom of the sliding grooves 1-3-3 adapted to the two ball rails 1-2 on the bottom surfaces of the two wing plates; two rows of fourth threaded holes 1-3-2 are arranged on both sides of the surfaces of the two wing plates, which are respectively used to connect two groups of width-adjustable clamping assemblies 2; a through-hole 1-3-1 is arranged in the middle of the cross beam; with the assistance of the wing plates, the whole support plate 1-3 is installed on the bottom plate 1-1 through a sliding locking member, and can slide and lock on the bottom plate 1-1 along the limiting chute and the ball rail 1-2.

[0086] The sliding locking mechanism includes a base plate slider 1-5, a locking bolt 1-6, and a locking nut 1-7. For example... Figure 5 As shown, the base plate slider 1-5 is located within the limiting groove and can move along the limiting groove. It includes a main body 1-5-1 and two side plates 1-5-2. The main body 1-5-1 is a hollow cylinder with counterclockwise threads engraved inside. The two side plates 1-5-2 are symmetrically arranged on both sides of the main body 1-5-1 near the bottom surface. The side plates 1-5-2 are "T"-shaped, and the main body 1-5-1 protrudes relative to the side plates 1-5-2. The locking nut 1-7 has clockwise threads engraved inside. The locking bolt 1-6 is installed at the through hole 1-3-1 of the crossbeam. Its upper end has clockwise threads engraved to cooperate with the locking nut 1-7, and its lower end has counterclockwise threads engraved to cooperate with the base plate slider 1-5. By tightening the locking nut 1-7, the support plate 1-3 is fixed to the base plate 1-1, preventing it from moving on the ball slide rail 1-2.

[0087] like Figure 1 As shown, two sets of adjustable-width clamping assemblies 2 are used to stably clamp the theodolite to be repaired, and are symmetrically installed on the two wing plates of the support plate 1-3. Each clamping assembly includes a rib plate 2-1, a clamping plate 2-6, a connecting adjustment component, and a support adjustment component; the clamping plate 2-6 is installed on the inner side plate of the rib plate 2-1 through the connecting adjustment component; with the assistance of the connecting adjustment component, the distance between the clamping plate 2-6 and the rib plate 2-1 is adjustable; the support adjustment component is installed on the clamping plate 2-6, and its height on the clamping plate 2-6 is adjustable; when clamping the theodolite to be repaired, the support surface of the support adjustment component makes surface-to-surface contact with the theodolite to be repaired.

[0088] By definition, the side closer to the center line of the base plate 1-1 is the inner side, and the side farther from the center line of the base plate 1-1 is the outer side.

[0089] like Figure 7 As shown, the vertical cross-section of rib 2-1 is inverted "T" shaped, and its lower panel corresponds to the flange, with two rows of third threaded through holes 2-1-1. The two ribs 2-1 are mounted on the two flanges respectively by set screws, face to face, and both perpendicular to the base plate 1-1. To make the load-bearing capacity of the entire rib 2-1 more reliable, reinforcing plates are provided at both ends of the rib 2-1, and the reinforcing plates are isosceles trapezoidal. A mounting through hole 1-3-1 is provided on the upper plate of the rib 2-1 near the top along the centerline.

[0090] like Figure 9As shown, the connecting adjustment component includes a thin-walled internally threaded cylinder 2-3, a thin-walled through-hole cylinder 2-4, a width adjusting bolt 2-5, and four guide rail cylinders 2-2. The thin-walled internally threaded cylinder 2-3 and the thin-walled through-hole cylinder 2-4 are respectively welded to the two ends of the mounting through-hole 1-3-1 on the rib plate 2-1, and the inner diameters of both the thin-walled internally threaded cylinder 2-3 and the thin-walled through-hole cylinder 2-4 are the same as the diameter of the mounting through-hole 1-3-1; wherein, the thin-walled through-hole cylinder 2-4 is located inside the rib plate 2-1, and the thin-walled internally threaded cylinder 2-3 is located outside the rib plate 2-1. The width adjusting bolt 2-5 passes through the thin-walled internally threaded cylinder 2-3 and the through-hole 1-3-1 sequentially from the outside to the inside, extending into the thin-walled through-hole cylinder 2-4, and the width adjusting bolt 2-5 is threadedly engaged with the thin-walled internally threaded cylinder 2-3, that is, the width adjusting bolt 2-5 is engraved with threads. Four guide rail cylinders 2-2 are vertically welded to the inside of the rib plate 2-1, serving as the four ends of the same rectangle. The thin-walled through-hole cylinder 2-4 is located at the center point of the rectangle. That is, the four guide rail cylinders 2-2 are arranged in pairs, symmetrically with respect to the thin-walled through-hole cylinder 2-4. Each guide rail cylinder 2-2 has a limit screw hole 2-2-1 for installing the limit screw 2-10 on its cylindrical surface near the end face.

[0091] like Figure 9 As shown, the support adjustment component includes a thin-walled sleeve 2-8, four width limiting slide rails 2-9, two support rods 2-12, two support rod bolts 2-11, and four guide rail sleeves 2-7. Thin-walled sleeve 2-8 and four guide rail sleeves 2-7 are welded to clamping plate 2-6. The installation position is determined according to the position of thin-walled through-hole cylinder 2-4 and four guide rail cylinders 2-2. After the guide rail sleeve 2-7 and thin-walled sleeve 2-8 are installed, the guide rail cylinder 2-2 and thin-walled through-hole cylinder 2-4 can move back and forth within the guide rail sleeve 2-7 and thin-walled sleeve 2-8. That is, the thin-walled sleeve 2-8 and four guide rail sleeves 2-7 are clearance-fitted with the thin-walled through-hole cylinder 2-4 and four guide rail cylinders 2-2 on the inner side of rib plate 2-1. Each guide rail sleeve 2-7 is provided with a through guide groove 2-6-2. The limiting screw 2-10 on the guide rail cylinder 2-2 can move axially within the through guide groove 2-6-2 to prevent the guide rail sleeve 2-7 from disengaging from the guide rail cylinder 2-2.
