Description

Technical Field

[0001] The present application relates to the technical field of cement mixing, and in particular to a cement mixing device and an anchor trolley. Background Art

[0002] Anchor trolleys are commonly used in construction areas such as tunnels and roadways. During operation, slurry must first be injected into the anchor hole, and then the trolley is used to insert the bolt. Because cement sets quickly, cement mixing equipment is often mounted on the trolley to prevent the slurry from solidifying. Currently, there is an increasing demand for grouting applications for anchor rods, cables, and other types of anchors on a single trolley. A single trolley with a single set of grouting equipment cannot meet the needs of multiple grouting pipelines. Multiple mixing drums on one machine impose high requirements on overall weight and design space, and are more cumbersome to operate.

[0003] After cement mixing equipment is completed, a large amount of mud will remain in the container. If it is not cleaned in time, the cement will solidify and affect subsequent mixing. In particular, the mud in the grouting pump is difficult to clean due to the small space. Therefore, there is an urgent need for a cement mixing equipment that can improve grouting efficiency and is easy to clean. Utility Model Content

[0009] Preferably, the longitudinal cross-section of the mounting portion is trapezoidal, and a seal is installed between the mounting portion and the protective shell, thereby preventing mud from entering the protective shell and causing damage to the shaft.

[0010] Preferably, a copper sleeve is mounted on the protective shell, wherein the outer diameter of the copper sleeve is smaller than the inner diameter of the protective shell; a lug is provided on the upper portion of the copper sleeve, wherein the outer diameter of the lug is larger than the inner diameter of the protective shell; and the shaft is rotatably mounted on the copper sleeve.

[0026] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0027] In the description of this application, it should be noted that for directional words, such as the terms "center", "horizontal", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and so on, indicating the orientation and position relationship are based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of this application.

[0028] It should be noted that the terms "first", "second", etc. in the description and claims of this application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0029] The terms "comprises" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, product or apparatus.

[0030] One aspect of the present application provides a cement mixing device, such as Figure 1 As shown, one of the preferred embodiments includes a mixing barrel 1 and a grouting pump 2; the number of the grouting pumps 2 is two (or three, four, five, etc.), and the multi-pump grouting mode can improve the grouting efficiency of the device and enable the mud in the mixing barrel 1 to be emptied as soon as possible, thereby avoiding the mud from being retained in the mixing barrel 1 for a long time and solidifying; in addition, in the actual working process, tunnels, bridges and other projects will be involved, and some falling rocks will inevitably occur. In order to minimize the probability of falling rocks hitting the grouting pump 2, the grouting pump 2 is designed to be rod-shaped, and the rod body of the grouting pump 2 must be perpendicular to the cross section of the mixing barrel 1.

[0031] Specifically, such as Figure 2 、 Figure 3 and Figure 4As shown, the grouting pump 2 is installed on the outside of the mixing barrel 1. The connection between the grouting pump 2 and the mixing barrel 1 can be through a connecting ring or directly through bolts. A connecting seat 3 is installed at one end of the grouting pump 2, and a cavity is provided inside the connecting seat 3. A first connecting port 31, a second connecting port 32 and a discharge port 33 are provided on the connecting seat 3. The first connecting port 31 is used to connect to the interior of the grouting pump 2, and the second connecting port 32 is used to connect to the interior of the mixing barrel 1. The discharge port 33 is provided at the bottom of the connecting seat 3, and the discharge port 33 is used to discharge mud. The first connecting port 31, the second connecting port 32 and the discharge port 33 are all connected to the cavity in the connecting seat 3 to form a three-way structure. The mud in the mixing barrel 1 can enter the grouting pump 2 with the help of the three-way structure, or be discharged through the discharge port 33.

[0032] It should be known that when the grouting pump 2 is grouting, the discharge port 33 should be in a closed state. Therefore, a detachable discharge cover 34 is installed on the discharge port 33; when cleaning is required, it is only necessary to open the discharge cover 34 to allow the mud to be discharged from the discharge port 33 under the action of gravity, thereby reducing the difficulty of cleaning the grouting pump 2.

[0033] It is understandable that there are many ways to connect the connecting seat 3 to the mixing barrel 1, but in order to ensure that the mud in the mixing barrel 1 can be emptied, the preferred solution is to connect the connecting seat 3 to the bottom of the mixing barrel 1.

[0034] In some embodiments, a conduit is inserted into the second connection port 32, and a slurry delivery port is provided on the mixing barrel 1. One end of the conduit communicates with the cavity in the connection base 3, and the other end is inserted into the slurry delivery port and communicates with the interior of the mixing barrel 1. It should be noted that if there is a height difference between the conduit and the bottom of the mixing barrel 1, the slurry in the mixing barrel 1 may not be emptied.

[0035] In some embodiments, a mounting plate is provided on the outside of the second connection port 32, and a slurry delivery port is provided on the mixing barrel 1. The mounting plate is fixedly installed on the mixing barrel 1, and the second connection port 32 is aligned with the slurry delivery port, thereby ensuring that the slurry in the mixing barrel 1 can be drained. In order to prevent the mud from seeping out from the side of the mounting plate, the mounting plate and the mixing barrel 1 should be sealed.

[0036] In this embodiment, if Figure 4 As shown, an installation section 21 is provided at one end where the grouting pump 2 is connected to the connecting seat 3. The installation section 21 is conical, and a gasket is installed inside the first connecting port 31. When the grouting pump 2 is plugged into the first connecting port 31, the installation section 21 squeezes the gasket to achieve sealing.

[0037] It is understood that the grouting pump 2, as a component that is frequently disassembled and installed, should be replaced as simply as possible. The mounting section 21 is designed to be tapered so that its outer diameter is much smaller than the inner diameter of the first connection port 31, thereby ensuring quick connection between the grouting pump 2 and the first connection port 31. Installing a gasket within the first connection port 31 not only increases friction between the mounting section 21 and the first connection port 31 but also prevents slurry from splashing out of the grouting pump 2.

[0038] It should be noted that the cement mixing device body will vibrate during operation, so the connection between the grouting pump 2 and the mixing barrel 1 should have high stability.

[0039] In this embodiment, if Figure 2 and Figure 3 As shown, a support member 100 is installed between the grouting pump 2 and the mixing barrel 1. The support member 100 is T-shaped, with one end of the support member 100 fixedly connected to the grouting pump 2 and the rest of the support member 100 fixedly connected to the mixing barrel 1. The grouting pump 2 and the mixing barrel 1 are both connected to the support member 100 by threaded engagement.

[0040] It can be understood that, according to the principles of mechanics, setting the support member 100 into a "T" shape can form a triangle-like installation structure between the support member 100, the grouting pump 2 and the mixing barrel 1. The triangle has strong stability, thus preventing the grouting pump 2 from shifting or even falling off due to the vibration of the mixing barrel 1.

[0041] In this embodiment, if Figure 3 and Figure 5 As shown, a drive assembly 4 is installed inside the mixing barrel 1, and the drive assembly 4 includes an agitator 41, a protective shell 42 and a shaft 43; the protective shell 42 is fixedly installed inside the mixing barrel 1, and the shaft 43 is at least partially installed inside the protective shell 42. A mounting portion 430 is provided on the upper part of the shaft 43, and the longitudinal cross-section of the mounting portion 430 is trapezoidal; the agitator 41 is fixedly installed on the mounting portion 430.

[0042] It is understandable that the drive assembly 4 is arranged in a detachable installation form, which facilitates the individual replacement of a part when it is damaged, thereby reducing the maintenance cost of the parts.

[0043] It should be noted that during the rotation of the agitator 41, the slurry tumbles, and the slurry can easily enter the protective shell 42 through the gap between the mounting portion 430 and the protective shell 42, thereby damaging the shaft 43. Therefore, a seal 400 is installed between the mounting portion 430 and the protective shell 42 to seal the interior of the protective shell 42 and prevent slurry from entering the protective shell 42.

[0044] In this embodiment, if Figure 5 and Figure 6 As shown, a copper sleeve 300 is installed at the opening of the protective shell 42, and the outer diameter of the copper sleeve 300 is smaller than the inner diameter of the protective shell 42, so that the copper sleeve 300 can be embedded in the interior of the protective shell 42; a sleeve ear is provided on the upper part of the copper sleeve 300, and the outer diameter of the sleeve ear is larger than the inner diameter of the copper sleeve 300 to limit the copper sleeve 300 vertically downward; the shaft 43 is partially rotatably installed inside the copper sleeve 300.

[0045] It is understandable that the cement mixing device drives the agitator 41 to rotate through the shaft 43, and the shaft 43 is prone to deflection during rotation, causing friction between the shaft 43 and the protective shell 42 and damaging the shaft 43. In this application, a copper sleeve 300 is installed between the protective shell 42 and the shaft 43, which not only limits the deflection angle of the shaft 43, but also prevents the shaft 43 from scratching the protective shell 42.

[0046] In this embodiment, if Figure 2 and Figure 3 As shown, the inner wall of the agitator 41 is provided with a plurality of stoppers 11, which are evenly distributed along the circumference of the mixing barrel 1, and the upper surfaces of the stoppers 11 are flush with the vertical direction of the mixing barrel 1. A channel is provided inside the stoppers 11, and a connecting block 12 is provided on the outer wall of the mixing barrel. The connecting block 12 is provided with a water inlet that is connected to the channel.

[0047] It is understandable that water needs to be added to the mixing barrel 1 when mixing cement, so components such as hydraulic joints can be installed on the mixing barrel 1, and water injection and spraying can be performed with the help of channels.

[0048] In this embodiment, if Figure 3 As shown, a filter element 200 is installed on the upper part of the mixing barrel 1, and the upper surface of the limit block 11 is used to limit the filter element 200 vertically downward; a pressure cover 201 is installed above the filter element 200, and the filter element 200 is used to filter the mud. The pressure cover 201 is used to seal the mixing barrel 1 to prevent impurities from entering the mixing barrel 1 and causing damage to the components inside the barrel.

[0049] It is understood that the filter element 200 is relatively large in size and weight, making manual replacement difficult. Therefore, a lifting lug is provided above the filter element 200, which can be used to replace the filter element 200. To facilitate the removal of the gland 201, a perforation and a handle are provided on the gland 201. The lifting lug passes through the perforation and limits the gland 201, so that the filter element 200 can simultaneously drive the pressure plate for removal.

[0050] Another aspect of the present application provides an anchor trolley, a preferred embodiment of which includes an anchor trolley body and the above-mentioned cement mixing device; the anchor trolley in the present application is a prior art, the cement mixing device is installed on the anchor trolley, and the grouting pump 2 can be used with a hose to transport the mud to the grouting equipment at the anchor thrust arm for grouting.

[0051] The above describes the basic principles, main features, and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above-described embodiments. The above-described embodiments and the specification merely illustrate the principles of the present application. Various changes and improvements may be made to the present application without departing from the spirit and scope of the present application. These changes and improvements fall within the scope of the present application for which protection is sought. The scope of protection claimed by the present application is defined by the appended claims and their equivalents.
